The first Hangover took everyone by surprise and is now a favorite movie of many.  It brought Bradley Cooper and Zach Galifianakis to the forefront and they are now superstars in Hollywood.  When I heard they were making a second Hangover I couldn't wait to see what they were bringing to the table. 

They released a teaser trailer a couple months ago, but now the full trailer has hit the internet and The Hangover Part II looks just as awesome as the first.  This new extended trailer even reveals that Ken Jeong is even back for a second adventure, this time in Bangkok.  Start the countdown to Memorial day weekend because that is when it is due out.
