This will keep you busy:
1. If a chicken says, "All chickens are liars" is the chicken telling the truth?
2. A father and son went in their car for a road trip. They got in a car crash. The father died, and the son was badly injured. He needed surgery, but in the hospital when the doctor comes in, the doctor says, "I can't operate on this boy, he's my son." Who's the doctor?
3. Two cops walked into a room with no windows and found a dead man who obviously hung himself from the ceiling, though they couldn't figure out how. There was no chair beneath him that he might have jumped off, of, or a table. Just a puddle of water. How did he do it?
