Best Superman joke I ever heard:
Clark Kent walks into a safe no other exit but the door he walked in.
Superman walks out of the safe. No one else is in the safe after he leaves.
Deduction Superman ate Clark Kent.
Mine is:
Waiter: "May I offer you a soup or salad?"
Clark Kent: "A super salad? *laughs nervously* How about a regular salad? A REGULAR SALAD FOR A REGULAR MAN."
