I picked up a couple of passengers in my cab the other day on the Upper West Side who told me with some enthusiasm that they wanted to go to Carnegie Hall.   I could see they were in a good mood, so I thought they might be candidates for the oldest joke in the world.

I fed them the line...

"How do I get to Carnegie Hall?"

They were right on it.

"Practice!" they called out in unison.

I paused for a few moments and gave this some serious consideration.

Finally I replied...

"Nah... I think I'll just take Broadway down to 57th Street and make a left."
