An American doctor and a Cuban doctor are having drinks...

.. and bragging about how good they are in their fields.

The American doctor says "I can do a kidney transplant in 4 hours."

Cuban doctor says "I got you beat. I can do it in 3."

The American doctor says "I can do open heart surgery in less than 3 hours!"

Cuban doctor says "That's nothing. I can do it in one and a half."

The American doctor says, "I can do an appendectomy in 1 hour."

Cuban doctor says "Sir, I can do one in the time it takes to hard boil an egg."

The American doctor, flustered, mutters "Well, I can remove someone's tonsils in about 15 minutes."

The Cuban doctor sighs, "Well you have me beat there, friend. Tonsils requires a 6 to 8 hour operation in Cuba."

The American doctor, confused, asks "What? Why would it take such an easy procedure so long??"

The Cuban doctor replies, "Well, in America, you can just open the patient's mouth and remove the tonsils. But in Cuba, since we can't open our mouths for anything, we need to reach in and pull the tonsils out through the patient's asshole."
