'The Hangover 2': 'Extra' Truth or Dare

First up was Bradley Cooper, who chose "Truth," and complimented Terri on her "beautiful eyes. 'Cause you're both very beautiful," he said Renee and Terri.

A braver Ed Helms went with "Dare," and Bargh asked him to make "the ugliest face you can think of." He succeeded in his dare, with Zach commenting, "That's good."

Cooper urged Galifianakis to "do a Dare," and Zach replied, "'Cause my whole life is embarrassing!" The comedian was asked to imitate one of his co-stars, to which he announced, "I will do an impression of Bradley looking into the mirror... you know what? No, it takes too long!" Cooper simply responded, "Wow."

Terri double-dared Galifianakis to "kiss someone in this room on the lips." Bradley egged his co-star on saying, "Wow, buddy, go for it!" Zach walked straight to "Extra's" audio crew member and planted one on his lips. "Had my eyes on you... and my lips on you," Galifianakis said after the smooch.

Watch the guys recover from their craziest hangover yet... the guzzling begins May 26.
