WARNING: This trailer contains explicit language and a NSFW shot of Chris Hemsworth's BIG wang!
Warner Bros. released the first red-band trailer for "Vacation," the reboot/sequel to National Lampoon's classic 1983 comedy.
The highly-anticipated flick stars Ed Helms as a grown-up Rusty Griswold, who opts to redo his childhood vacation to Walley World with his own family.
Christina Applegate plays his wife, while Leslie Mann fills the role of sister Audrey. But, don't worry, "Vacation" veterans Chevy Chase and Beverly D'Angelo reprise their roles as Clark and Ellen Griswold.
In true Griswold form, the family trip is filled with not-so-family-friendly hiccips, including a dip in a sewage pond, conversations about glory holes and a close encounter with Hemsworth's abs and Thor's huge, uh, hammer.
You don't want to miss the trailer above -- just make sure your boss isn't watching!
"Vacation" opens in theaters on July 31st.
