"…And of course Mercedes and Sam would sing Black or White!"

Tina covered her eyes with a hand. "Oh. Rachel. No."

Sam and Mercedes both raised their heads sharply from whispering to each other. Mercedes turned toward him in her chair at the lunch table. "Did she just say what I think she just said?" He just nodded, giving Rachel a look that Puck amusedly noted was identical to Mercedes' I'm-Judging-You face. Mercedes pursed her lips sassily. "Berry, when we sang Christmas carols at the homeless shelter, did I suggest that you start singin' I Have a Little Dreidel because you're Jewish?"

Rachel glanced at Finn who was staring down at his tray of food like a deer caught in headlights. "Well…I…it just seemed like that song would be relevant to your…" Her voice started to falter as several members of the glee club began shaking their heads. "…relationship?"

Sam smirked. "You want something relevant? We should sing Rock With You."

Mercedes had started to nod at his suggestion but paused, thinking through the words of the song. She felt her face gradually get warmer and warmer. "…Sam!"

Santana leaned forward in her seat across from the couple, suddenly interested. "Really? That song is relevant to you two? Which part? 'There's a magic that must be love'? That seems cheesy enough for you, Evans." Beside her, Britney chuckled.

Sam also leaned forward; crossing his arms on top of the table. "More like 'let that rhythm get into you', 'you got to feel that heat', and 'just take it slow'."

Puck whistled his appreciation, and Mike grinned. Mercedes buried her face in her hands. "Oh God, Sam, shut up. Please shut up."

Santana laughed at her friend's obvious embarrassment. "Oh no, please keep talking. I wanna hear all about this."

Sam raised an arm to rest it across his mortified girlfriend's shoulders and began to sing softly.

Girl, close your eyes

Let that rhythm get into you

Don't try to fight it

There ain't nothin' that you can do

Mike kissed Tina on the cheek and joined in.

Relax your mind

Lay back and groove with mine

Puck winked at Quinn. She rolled her eyes but couldn't help but grin as he sang the end of the verse.

You got to feel that heat

And we can ride the boogie

Share that beat of love

Mercedes lowered her hands from her face and grasped Sam's arms. Her voice was a pleading whisper. "Baby, you weren't here to see it or suffer through it but the last time we sang in this cafeteria, people tried to kill us with food. Please don't…"

Sam stood, facing her. Puck and Mike followed his lead.

I wanna rock with you all night

Dance you into day, sunlight

I wanna rock with you all night

We're gonna rock the night away

Mercedes glowered at Santana. The other girl shrugged, still laughing. "Lo siento, girl. I didn't know Sam had game now."

Sam fist-bumped Mike and then Puck and sat back down, figuring he had embarrassed his girl enough for one lunch period. "Why thank you, Santana."

Mercedes gave a sigh of relief. "And thank you for not continuing."

"Oh don't worry, babe." She raised an eyebrow and turned to him. His arm took its place again across her shoulders, and he gave her a squeeze. "You'll hear the rest of the song in glee club next period."
