Three of the film's leads -- Ed Helms, Zach Galifianakis and Ken Jeong -- took time off from participating in the latest edition of the bachelor party series to watch the First Lady give a speech at Orr Middle School in Las Vegas. She had been in Los Angeles the day before, appearing on Jimmy Kimmel Live! and attending a fundraiser at the home of Will Smith.

Nevada is a crucial swing state, and is receiving significant attention from the Obama campaign; the president spoke at a high school in North Las Vegas just two days before.

The Hangover trio did not factor into the First Lady's speech, but they did help encourage early voting, and spoke with Dem Rep. Shelley Berkley, who is running for senate. They also paid a visit to Obama campaign headquarters in Vegas.

Galifianakis made some political waves earlier in the year, when while promoting his satire film The Campaign, he called the conservative industrialist David and Charles Koch "creepy" and said he didn't agree with their actions.
