I've been a fan of Lateral Thinking Puzzles since I was about 12.  The coining of the phrase Lateral Thinking was done by Edward de Bono.

This particular game Lateral Puzzles : Series #1 has 100 puzzles with a few ads thrown in.  I've done 50 in about 30 minutes. Many are old. Some have spelling mistakes.
I'm attaching just 1 image. The solution made me laugh.
