Doctor's Enema

A man goes to a doctor and says he's having problems shitting, so the doctor gives him an enema and says he needs to do it a few times at home, but does the first one for him. So the guy bends over the table, lubes him up, and shoves it deep in him, and he yells.

So later, the man goes home and tells his wife he needs her help with the enema. So he bends over, she lubes him up, puts a hand on his shoulder, and she shoves it up there, and he starts screaming and cussing, and the wife asks, "Did I hurt you?" He said, "No, I just realized when the doctor did it, he had both hands on my shoulders."
