They'll look like fools!

Here are some invaluable ways to make your gullible friends look like fools.  Be careful when you use them, they will most certainly never work again.

1. "It's impossible not to get dizzy if you move your head back and forth with your mouth open" Instant classic
2. "70% of people can't touch their thumb knuckle to their bottom teeth more than 10 times without getting dizzy." Dizzy is a common theme
3. Best for last: "If you pour a closed salt shaker into your mouth, it will still taste like salt."

You'll look like him, a fool with cowboy boots and shorts
