This is a test to try on your friends.
It's funny watching them try.
Get them to sit cross legged, with their back straight, then get the to chose a leg, which the lift their knee up to their head.
Then tell them to straighten their leg, with out moving their head from their leg, or moving their body.
Works best if they aren't flexible.
Tried this on my sister...funny as hades. Or more funny as Rick Riordan.
