Gapfiller?

Watched 214 last night and thought of this. Can't even remember if it was a gapfiller or not, but it had Brian bringing in a sling to "play" ... Justin broke down and finally told Brian what had happened at Sappenstein's party. Does that ring any bells?

ETA: Thank you, flamingjunie! It's "Roughfucked" by London starting here.
