Gears of War Easter Egg - Rooftops - Man on the Toilet

In versus multiplayer, online or offline, on the map Rooftops you can see a man sitting on a toilet (which many people believe he is going "#2", for no apperent reason). I believe it is the COG side at the beginning of a match (the teams switch sides each round, anyhow), but on one of the sides if you follow the path to where the first building is that has a Hammer of Dawn, if you look across from that building to another appartment there should be a few windows in it and two broken windows (note that the other side has a fence blocking the way). Throw a smoke grenade through one of the broken windows and wait for it to spread to see the silhouette of a man on a toilet, presumably dead.
