A new trailer for “The Hangover 2” has arrived. Watch it and see if you can count all the similarities to the first “Hangover.” I’ll get you started: there’s a celebratory toast; our three “heroes” wake up in a hazy stupor (this time in Bangkok, not Vegas); there’s something very wrong with Ed Helms’s appearance; and instead of finding a tiger in the bathroom, they find a monkey.

Oh, also? Zach Galifianakis still makes really awful speeches to congratulate people on getting married.
