Watch the First (Pretty Gross) Trailer for 'Dumb and Dumber To'

Harry and Lloyd are back...and they're just as inappropriate as ever.

The first trailer is out for "Dumb and Dumber To" and it's chock full of the kind of gags that we saw in the original hit comedy. There's Harry (Jeff Daniels) trying to pull a catheter out of Lloyd (Jim Carrey), there's a particularly funny phone gag between the two, and there's an especially gross bit toward the end. Watch at your own peril.

Here's the story, according to the trailer: Harry and Lloyd reunite after a very long and elaborate prank, and discover that Harry might have a daughter. That sparks a cross-country search for the girl, who happens to be very attractive, making things awkward for Lloyd.

But really, the plot is just a base with which to serve us the delicious dumplings of slapstick comedy that the original movie did so well so many years ago. Not much has changed, despite the time gap: Harry is still living in the same apartment, and we get a glimpse of the dog van. He does have a cat now, though, which worries us. The bird didn't turn out so well.

Jim Carrey and Jeff Daniels are joined by a comedic supporting cast, including the likes of former "Daily Show" correspondent Rob Riggle, and "The Walking Dead" star Laurie Holden.
