Bobby is peeved at Eddie after an incident happened in the bathroom at work.
Both Bobby and Eddie walked into the bathroom, Bobby went in just to wash his hands while Eddie went to use one of the stalls. Bobby saw Eddie do a circle out of a stall and Eddie warned everyone "don't go in there." Bobby was shocked that Eddie wouldn't just flush the toilet for the next person who comes along.
Bobby was the only person on the show who said they would flush the toilet after someone else. Everyone else admitted they would see it and turn around like Eddie did, or just avoid a stall like that altogether. Bobby says this is what's wrong with humanity because people should be looking out for each other. He thinks we should all collectively be flushing toilets if we see something in one, even if it's not ours.
Eddie joked that people should "Do an Eddie" and just warn your friends of a bad stall.
