Honestly I had a lot of trouble with that scene. There isn't much dialogue to work with.
I hope my comment didn't come off as sounding critical. I actually think the repeated "she's been gone a month" line is hilarious.
The "four of us went out, thirty of us came back" line would be extra funny if a bunch of people could be composited into the background, just wandering around.
