Toilet Monster

Toilet monster is a mysterious man who have keys to every home, comes in the middle of the night when everyone sleeps, shits in their toilet, then takes a shower and leaves. The only way to catch him: when he leaves he never wears underwear beneath his clothes!! (If you catch somebody late night, leaving your house after taking a dump and you undress him and he have underwear on him, it is just an ordinary pervert so let him go!)

Man, my water-pipe broke in my flat, luckily my neighbour gave me their keys to watch the house while they are on the vacation. I will be such a toilet monster.

Peter Griffin was such a toilet monster when he found out Cleaveland's house is empty.
