2. "10 Bets You Will Never Lose"
From the quirky mind of Richard Wiseman comes this British-voiced "how to" video that scored almost 4 million views in its first 5 days. This video shows ways you can trick your friends into giving you their money with slight-of-hand and physics-challenging stunts that involve matchsticks, glasses of beer, and 20 pound notes. (U.S. participants, feel free to use a 20 bill if the Queen's currency isn't handy.) Other titles from this video maker include "10 Amazing Practical Jokes" and "10 Quirky Science Stunts."
