This site is a riot! Go to Peter, Please Answer and ask a question. If you do it right, Peter will know the answer.
It works like this:
You need a typer, and a person to ask a question.
the typer is in on the trick.
The typer says "ask any question, and Peter will know the answer."
So the skeptical person will ask something like "What's my dogs name?"
The typer types the question into the computer, and WOW! Peter Knows!
"Sparky-Boo-Boo-Doggy" appears on the computer screen in big bold letters.
The person is amazed and asks several more questions.
How does it work?
Peter takes over the keyboard. When the typer is supposedly typing the question, he or she is actually typing the answer.
Try it. Its a blast!
