Chris Hemsworth And His Massive 'Vacation' D**k Are The Official Stars Of CinemaCon

Yeah, we went there.

When a giant audience of theater owners, press, and so on and so forth packed into the The Colosseum at Caesars Palace for the Warner Bros. presentation at CinemaCon on Tuesday (April 21), we all expected to be blown away by footage from "San Andreas," "Mad Max: Fury Road," "Magic Mike XXL" and the rest of the studio's blockbuster fare.

And don't get us wrong -- we totally were. But surprisingly, it was a short trailer from the upcoming sixth installment of the "National Lampoon's Vacation" series, "Vacation," that had the audience in stitches. Mostly because of Chris Hemsworth's giant d--k.

Okay, okay, so the d--k itself was probably fake. But the trailer was a two minute-plus raunchy, R-rated blast that featured Clark Griswold's grown up son Rusty (Ed Helms) embarking on a brand new vacation to Walley Word with his wife Debbie (the incomparable Christina Applegate) and their two foul mouthed sons. To say it was a crowd-pleaser would be an understatement, and the biggest laugh of the entire Warner Bros. presentation came when Hemsworth showed up onscreen, wearing a giant prosthetic (we assume) d--k that shocked Debbie, Rusty, and all of us here at MTV News with its beautiful in-your-face-ness.

Find out what Applegate and Helms had to say about Hemsworth in the video below, then be sure to check out "Vacation" when it hits theaters on July 31, 2015.
