Sponge Mistake

In the doctors office two patients are talking.

"You know, I had an appendectomy last month and the doctor left a sponge in me by mistake."

"A sponge!" exclaims the other. "And do you feel much pain"

"No pain at all," says the first, "but do I get thirsty!"

Sure glad this didn't happen to me with my knee surgery a few weeks ago!
