I Happen To Think Singing Is Hilarious,

Let's Just Say It Was Damn Hard [to Make The Hangover]. I've Got The Bumps And Bruises To Show For It. It's Funny Because Things That Don't Even Look That Bad On Screen Were Still Extremely Painful.

I Found Myself Often Asking The Question, "who Deserves To Be Made Fun Of?" Depending On Your Mood, The Answer Can Be No One Or Everyone. It Took Me A While To Understand The Math Of How Those Field Pieces Came Together. I Don't Think That Ridicule Is Ever Funny, But There Are Times When That Gets The Biggest Response.

As Much As You Do Get Beat-up Doing Even Small Action Sequences, It's Incredibly Fun.

To Be Totally Candid, It Was Really Born Out Of A Panic Attack The Summer Between My Sophomore And Junior Years, When I Realized I Wasn't Going To Graduate In Four Years Unless I Somehow Managed To Glue Together All The Courses I'd Taken. That Said, I'm Really Glad I Did It, 'cause It Was Really Fun, And I Was Able To Just Take Whatever The Hell I Wanted.

When We Were Not Shooting [the Hangover] We Were Sleeping, So Pretty Much Every Waking Moment We Spent Together. And, You Know, Bradley [cooper], Zach [galifianakis] And I Were Acquaintances Before The Movie Started But We Became Good Friends Very Quickly And Spent So Much Time Together That It Was Just Inevitable We Were Either Going To Really Hate Each Other Or Really Like Each Other. Thank God It Turned Out To Be The Latter.
