I was just reading an Andy Samberg/Justin Timberlake romantic fanfic (?!?? I KNOW, what the hell am I doing?!?) and it had this line:
"When Andy was joking around during the end of season promo, he wasn’t really acting. Honestly, Justin thinks that Andy might not know any other way to kiss besides wrapping his arms too tight around Justin’s torso and surging up for a kiss until his intended target (again, Justin) gives in.."
So, obviously I had to find said promo. And it was worth it.
