Ghost Rat in the Bathroom

Squirrel announces, calmly, as if this is an everyday occurrence, as he is coming out of the bathroom- with just the tiniest bit of surprise, "I just saw a ghost rat in the bathroom. It jumped out of the toilet and went through the doorknob. Maybe it wasn't a rat. It might have been a mouse or something else. But it went through the doorknob."

Ghost Rats. Who'd a thunk it?
