He's not doing sheep, sillynuts - he's doing INFLATABLE sheep. There's a difference - the former is a felony, the latter is high comedy!
Yes, the guy screwing inflatable animals could get a curtain too...but if it was a choice between moving my company and getting a curtain, guess which one I'm taking?
I don't know if its a felony in the UK, but I'm sure its illegal.
In most of the states in the US its certainly illegal, but not all. Some states have removed any criminal penalty for sexual conduct with an animal, undoubtedly figuring that a jail is not the appropriate place to put someone that sick.
