With "The Hangover," co-writers Jon Lucas and Scott Moore helped turn four hard-partying idiots and one crazy night into a billion dollar (and counting) franchise. So it only makes sense that they'd follow a similar formula for their directorial debut, "21 and Over," which is another feature-length ode to drunken debauchery, only set at college instead of Vegas.

It all starts when Casey (Skylar Astin) and Miller (Miles Teller) show up to surprise their high school buddy Jeff Chang (Justin Chon) and take him out for his 21st birthday. The only problem is, he has an important med school interview the next morning, and a seriously intimidating doctor dad (Francois Chau) who's more interested in pressuring his son into following in his footsteps than celebrating his birthday.

But because one quick beer and a midnight curfew wouldn't make for much of a movie (let alone a 21st birthday), the trio's semi-responsible evening soon turns into a marathon night of bar-hopping, which makes a seemingly easy task like taking a passed-out Jeff Chang home into an epic quest.

So just how wild did the guys' night get? And can "21 and Over" possibly reach the debased heights of "The Hangover"? To find out, I crunched the numbers.
