I love shitting on beds!

I love to shit on other peoples beds!
it always gets my adrenaline pumpin.. every time i visit a friends house. i just take a steamy shit all over his comforter..and every time they come back in to there room! i stare at him , trying to act completely oblivious to the fact that there is a big pile of shit on his bed!! He will ask me! "did you just leave that steamer on my bed?" and ill say!....................."no, it was your aunt sheila sleep walkin again" and then i will go home just waiting for another friend to inite me over so i can do the do again! is this normal?
