Do you think Frankenstein has ever held in a dang fart?

Yes, and that's why he's green.

The doctor or the creation? I'll bet the creation could clear a room easy.

Im.not sure the doctor would have actually made him a butthole. Which is an integral part of the whole farting thing. Such a thing would be almost like art with all the detail that with entail. So my answer is no. Final answer.

i haven't thought about it

I think he just lets them dang things rip
