A man with a bad stomach complaint goes to his doctor and asks
him what he can do. The doctor replies that the illness is quite
serious but can be cured by inserting a suppository up his anal
passage. The man agrees, and so the doctor warns him of the pain,
tells him to bend over and shoves the thing way up his behind.
The doctor then hands him a second dose and tells him to do the
same thing in six hours.

So, the man goes home and later that evening tries to get the
second suppository inserted, but he finds that he cannot reach
himself properly to obtain the required depth. He calls his wife
over and tells her what to do. The wife nods, puts one hand on
his shoulder to steady him and with the other shoves the medicine
home.

Suddenly the man screams, "DAMN!"

"What's the matter?" asks the wife. "Did I hurt you?"

"No," replies the man, "but I just realized that when the doctor
did that, he had BOTH hands on my shoulders!"
