Abie, a somewhat shy and retiring gentleman who lives a bit southwest,
sent this one...

Albert Einstein was once traveling from Princeton, NJ on a train when the
conductor came down the aisle, punching the tickets of every passenger.

When he came to Einstein, Einstein reached in his vest pocket. He couldn't
find his ticket, so he reached in his trouser pockets. It just wasn't there. He
looked in his briefcase but couldn't find it. Then he looked in the seat beside
him. He still couldn't find it.

The conductor said, "Dr. Einstein, I know who you are. We all know who you
are. I'm sure you bought a ticket. Don't worry about it."

Einstein nodded appreciatively.

The conductor continued down the aisle punching tickets. As he was ready to
move to the next car, he turned around And saw the great physicist down on
his hands and knees looking under his seat for his ticket.

"The conductor rushed back and said, "Dr. Einstein, Dr. Einstein, don't worry,
I know who you are; no problem. You don't need a ticket. I'm sure you bought
one."

Einstein looked at him and said, "Young man, I too, know who I am. What I
don't know is where I'm going."
