Blaine pulled his brother's BMW into the Costco gas line just as the warning light flashed on the dashboard.

"Isn't this a membership place? Do you even have a Costco card?"

"Right here," Blaine said, reaching into the visor pocket.

Cooper had told him about the card — and the cheap fuel — when he loaned them his car for their week in L.A.

"It's over by the airport. Cheap gas and jumbo packs of condoms. What could be better?" Cooper told him with just a bit too much enthusiasm.

Unfamiliar with the car, Blaine pulled up to the wrong side of the pump, but figured he could make the hose stretch across the sedan. He hopped out, a bit of a dance to his step as he kept humming to the song they had be listening to on the radio.

"Oooooh, we're half way there. Oh-oh, livin' on a prayer," swaying his hips and swiping the card.

Overhead, at the top of the pump, the news played on a video monitor.

"And in Russia today ... hey you! The singer at Pump 16! Nice pipes!"

Blaine stopped, froze in his tracks for a moment, and shifted his eyes from side-to-side, trying to attach voice to face.

"I said nice voice!"

Blaine jumped back when he realized the voice belonged to the newscaster.

"Yeah! Up here! PumpGas News! You sing professionally?" the broadcaster asked.

"Kind of. A couple of shows and a lot of karaoke."

"You like karaoke?"

"We love it," Blaine said, angling his head toward Kurt, who was still bobbing his head to the radio.

In the car, Kurt looked around when he realized he hadn't heard the sound of the metal nozzle hitting the gas tank. He looked over his shoulder to see Blaine talking to the gas pump. He ducked lower in the seat, and turned the radio down to try to eavesdrop.

"I'll make you a deal," the newscaster said. "You sing us a song, and PumpGas News will pick up the cost of your gas today."

"Great!" Blaine exclaimed, never one to turn down a solo. "What do you want to hear?"

"What do you sing?"

"Everything! But I really love a good pop song — P!nk, Katy Perry ... How about some Daft Punk?"

"You need the words?" the gas pump guy asked. "I've got the karaoke machine right here."

"Oh no. Igot this. But if you've got the background music forGet Lucky, punch it!"

Disco beats burst from the pump-top speakers, and Blaine burst into song.

We've come too far

To give up who we are

So let's raise the bar

And our cups to the stars

He set the nozzle back on the gas pump and started dancing with the song, circling his hips.

She's up all night 'til the sun

I'm up all night to get some

She's up all night for good fun

I'm up all night to get lucky

"DANCE BREAK!"

Blaine started shaking his ass, raising his hands and twirling, urging Kurt out of the car to join him.

"Dance with me, Kurt! We're getting free gas!"

He brought his hands up in front of his face and then started backing it up, popping to the rhythm.

"And our singer can twerk!" the fake newsman said.

Kurt was nearly choking on his laughter, doubled over in the passenger seat, covering his face with his hands.

We're up all night 'til the sun

We're up all night to get some FREE GAS!

We're up all night for good fun

We're up all night to get FREE GAS!

"Hey, is that your boyfriend? He looks pretty embarrassed."

"Husband! As of two months ago," Blaine said, pointing toward Kurt with both hands, integrating it into his dance moves. He'd learned a few tricks from his brother over the years.

"Does he sing?"

"Like an angel! Kurt, come on and sing with me!"

"No!" Kurt shouted from the car, laughing and burying his face in his arms.

"We'll give you a gift card so you can come back for more gas if he sings, too," the PumpGas Newsman said.

In that instant, Blaine had a moment of inspiration. A gift card could come in handy.

The passenger side door opened slowly, and Kurt slid out, Blaine immediately wrapping an arm around his waist.

"Are you going to sing?" Blaine asked.

"No, no, no!" Kurt laughed.

"Your husband says you're quite a singer," the PumpGas Newsman said.

Blaine twirled back toward the gas nozzle, stretching it over to car's tank and swinging his hips from side to side. A small crowd of onlookers was starting to gather.

"There's a Costco gift card in it for us," Blaine said with a wink.

"Gnarls Barkley.Crazy. Hit it."

I remember when, I remember

I remember when I lost my mind

There was something so pleasant about that place

Even your emotions have an echo in so much space

With gas pouring into the car, Blaine slid in behind Kurt, singing backup vocals and lightly grabbing him by the hips, encouraging him to dance along with the song.

Kurt responded with his best, most practiced move: the shimmy.

Does that make me crazy?

Does that make me crazy?

Does that make me crazy?

Possibly...

He finished the song just as the tank hit it's limit. But Blaine, caught up in the moment, started singing another song, changing the lyrics toGive Up the Funkfor the occasion, and dancing around with the gas nozzle.

We need the gas!

Give up the gas!

We need the gas!

Gotta have the gas!

The onlookers were starting to dance around the pumps with the duo, some of them singing along.

"The newlyweds are getting free gas — and a Costco gift card!" the fake newsman cheered, doing his own little desk-side dance.

The crowd erupted in applause. Kurt took a little bow. Blaine squished his face into a scrunchy look of approval, nodding and bobbing his head.

Minutes later, the segment producers paid the Hummel-Andersons' gas bill, handed them a $50 gift card and sent them on their way, with thanks.

Kurt heaved a sigh, buckled up, and started to put the gift card away.

"Don't do that. We'll be putting it to use," Blaine said, smiling.

"We're giving the car back today, Blaine. We're not going to need more gas."

"But we are checking into a hotel, and you forgot Cooper's second-favorite Costco item."
