These are one of the funniest kind of jokes because the Medical profession is otherwise a serious profession.
Two 80 year old men are driving down the road when they hear the Ex-Lax commercial end with the statement: "It makes you feel young again."

John looks at Sylvester and says, "We need to pull over and get a bottle of that stuff!"

Sylvester agrees and the two old men pull over and get a bottle of Ex-Lax. They both take two tablespoons each and continue to drive.

About one mile later Sylvester asks, "Well John, do you feel young yet?"

"No," replies John.

So they pull over and take four more tablespoons a piece and continue to drive down the road.

A couple of miles later, Sylvester asks, "John, do you feel younger?"

"No," replies John, "but I sure did a childish thing!"
