In this episode when Rob is trying on the coat and looking in the mirror acting kind of femme, originally you can hear the janitor say, "I don't go for that" and then says "Does your mother know your doing this?" Now you can't hear him say that first line. Either way it cracked me up.
I goofed. He does say that first line a little earlier in the episode. It's a good thing I can go back to these episodes on youtube and check these out.
