1) There's an anon on the /mlp/ thread who keeps a BlueFast toy in a jar of his own cum 2) A man was arrested a couple months ago fucking a horse. Heh heh. Horsefuckers.
A cat whos ass smells like horse shit.
Cats putting their litterbox muscles in your face is not as uncommon as one might think, so you can get a snootful fairly readily. :-/
