Best bar tricks?

[davetrout]

Just wondering what's some of the best tricks you have seen in your local bar. For instance betting somebody you can skull  1 beer standing on 1 hand. The joke is to actually just bend over stand on your hand and drink your scooner with other hand.                 Cheers big ears

Offer someone 5 baht for every 10 baht coin they can stand on edge on the bar/table.

If they do 10 hand them 50baht and pick up the 10×10 coins.

You haven't lied and you've made 50baht.

Have seen foreigners and locals who seem to believe the best bar trick, is to leave the bill behind.
