For future reference, if you're ever throwing together a movie trailer in a hurry, make sure you take out the “monkey blowing a soda bottle in some guy's pants” part before screening it in front of a PG-13 audience.

Yes, Warner Brothers got their fingers smacked over simulated monkey sex in the trailer for Hangover 2. Apparently, monkeys blowing soda bottles are too risqué for the audience to which it was shown.

In a statement released after complaints were filed, Warner Bros. said, “In our haste to meet the placement schedule for this trailer, we failed to properly vet the final version with the [Motion Picture Association of America]. We acted immediately to correct the mistake and removed the trailer from screens.”

The trailer was slipped in before Source Code, a PG-13 movie in which Jake Gyllenhaal plays a man trapped in another man's body trying to save the world from a bomber in Chicago. And it seems without the monkey sex scene, the Hangover 2 trailer would have been okay. But Warner Brothers dropped the ball, and forgot to remove the monkey. And now the trailer's being edited and put on hold until it can be screened with R-rated Scream 4.

We think that we are most shocked that we can't find the trailer on the Internet. What's up with that?
