Two of my favorite riddles:
The man who made it has no use for it.
The man who bought it doesn't want it.
The man who received it doesn't know it.
What is it?
There are 3 men in a boat. They have 4 cigarettes.
But they have no way to make fire.
Yet they are all smoking. How?
The second one had been one of the (better) riddles from the Riddler on the old Batman TV series. Considering that some actual riddles were "What's yellow and writes? Of course, Batman! A Ball Point Banana!" and "What kind of people are always in hurry? The Russians." this one is pretty darn good.
My best friend Laughter's brother loved Frank Gorshin (The Riddler) and met him before Gorshin passed. Laughter's brother asked him this riddle to see if he still remembered it, and yes, yes he did!
Try and guess them before you just go ahead and highlight the answers.
They throw one cigarette overboard and make the boat a cigarette lighter!
