Scene in S5

[aishwaryarai68.livejournal.com]

Hey!

I just remembered a scene from QAF.

B & J are having a foursome, the other two guys are a couple. They are sharing a joint and talking about how long they've been together. Those two answer that for several years, but B and J answer at the same time, something like: J-"3 years" , B-"3 weeks", J-"It's complicated" . I'm not sure about the number though.

Does anyone remember in which ep was this?
Probably early S5, but I'm not sure. Help me, pls!

Edit:  Ep. 504
I know that many people hate that scene, and so do I, but I really wanted to watch it again...
Anyway, thx!
