Patrick seems pretty confident in his declaration that Derek must wear the sexy strappy chest thing, and he's about to laugh it off, but he hears the sound of a car door slamming somewhere down the street. He lifts his chin a little and narrows in on the sound, scenting cooked meat and sweet barbecue sauce as someone hurriedly climbs the stairs.

David and Patrick can hear none of this, of course, so Derek makes a big show of pulling himself to his feet with a hapless shrug.

"Well, if it is my turn," Derek sighs out, reaching for the hem of his shirt just as the delivery man approaches their door. Just as he lifts the fabric, a loud knock sounds the apartment, and Derek snaps his fingers and clicks his tongue.

"Aw, shucks. Missed my chance," he says, eyes bright with amusement as he turns on his heel. "I'll get the door."
