Found this joke. :O

Airport Security: What's your Name?

Passenger: Batman.

Airport Security: Your real name please.

Passenger : My name is Bat-Man.

Airport Security: Are you trying to be funny? What is your family name?

Passenger: Superman.

"Airport Security handcuffs him & put him into a locked security room.

Then they checked his Passport..."
