My favourite “broken telephone” (or whatever you wanna call it) scene.

I think the only context you need is that Nick and Cece work in the same bar, and Nick is talking about potentially adding a popcorn machine to the bar (he is against it), but Jess thinks Cece is in love with Nick and that’s what she is talking about. Also, Wiston (first guy you see) is just making stuff up for a reason I can’t remember.
