VIDEO : Ed Helms Jokes About Chris Hemsworth Prosthetic Prop

It's not easy being Chris Hemsworth.
The poor guy not only had to strip down to show off his incredibly hot body in Vacation, but he also had to parade around in one scene in a pair of tight underwear stuffed with an enormous fake penis.
His studly character, is a weatherman married to Audrey Griswold, played by Leslie Mann.
Co-directors and writers John Francis Daley and Jonathan M. Goldstein revealed that Hemsworth had a say in just how large his faux manhood would be.
Ed Helms said he wasn't surprised by the mammoth prosthetic. "I knew exactly how big it would be because it was molded off of me," the funny man cracked.
Vacation premieres July 29.
