Browsing through
Lifehacker today and I stumbled across a post titled,
5 sure-fire bar bets. Basically, they're 5 tricks you can do in a pub that look really convincing to the uninformed, so you bet a round that the reverse will happen and win a round - proposition bets.
The direct link to the article is:

) and the measuring one, which I'll admit looks really convincing. The hat one's just shifty though.
If you're not a betting or drinking person, they're still pretty cool party tricks. Try it on your friends the next time you're out.
P.S. Why can't we have shows like this on Australian TV, especially on Channel 10 who's target demographic is 18-39...
