"Black Eye" joke

An undertaker comes home with a black eye.

"What happened to you?"asks his wife.

"I had a terrible day," replies the undertaker.

"I had to go to a hotel and pick up a man who had died in his sleep. When I got there, the manager said they couldn't get him into a body bag because he
had this huge erection. Anyway, I find the room and, sure enough, there's this big, naked guy lying on the bed with this huge erection. So I did what I always do; I grabbed it with both hands and tried to snap it in half."

"I see," says his wife."But how did you get the black eye?"
The undertaker replies, "Wrong room."
