ive actually had a brown recluse in my toilet as well. A couple years ago when i was 5 or so, I went to the bathroom, lifted the seat, and there was this huge brown thing that looked like a cicada before it becomes an adult, the thing was about as big as 2 tennis balls. Well, i threw the lid down, flusehd, and ran to my dad, where we came and it was gone...scared the shit outta me
