Here's a small sampler of what's inside! � A farmer has twenty sheep, ten pigs, and ten cows.

Don't think too hard or you'll never solve these logic puzzles and riddles. The answers to all 187 are easy once you catch the tricky wording. How can you tie a knot in a napkin by holding one end in each hand without letting go of it? Impossible, you say (or your friends will say, if you bet them). But: Cross your arms and hold a tip of the napkin in each hand. When you uncross your arms, the knot will be formed! Now try this riddle: I climbed up a cherry tree, where I found cherries.

I did not "pick cherries," because I "picked a cherry." Take this dare: My bird can fly faster than any supersonic plane.
