It's been 25 years since the Farrelly brothers foisted Harry and Lloyd's dumbness upon us.

And for that, the people—if not people who are also film critics—owe them a debt of gratitude.

Dumb and Dumber was hardly the first ribald comedy to be a huge hit, and it wasn't the first full-length feature film to traffic entirely in nonsense, start to finish. It wasn't even the first Jim Carrey comedy to do that.

But whatever it was, be it the time—toward the end of the exciting movie year that was 1994—or perhaps the commitment that Carrey and Jeff Daniels brought to their roles and the surfeit of quotable lines, this ridiculous and completely hilarious movie remains a gem of the unapologetically un-PC, gross-out comedy genre.

"All this stuff we do that's so dumb, you can't believe we're so dumb," Daniels, theretofore known for more dramatic fare, said at the time while sharing how much fun he was having throwing intelligence to the wind. "We're a threat to national security, these two guys. We're trouble. As Jim says so often, we're out of control, and we don't even know it!"

Lest we forget, 1994—in addition to being the year of Forrest Gump, Pulp Fiction and The Shawkshank Redemption—was the year of the Jim Carrey movie trifecta that vaulted Fire Marshall Bill from In Living Color to super-star status, starting with Ace Ventura: Pet Detective in February, segueing to The Mask in July and concluding with Dumb and Dumber in December.

Though there could've been Carrey fatigue by then, moviegoers couldn't get enough, and Dumb and Dumber ended up making $127 million to end up the sixth-highest-grossing release of the year.

"Just two dumb guys driving cross country with a loose plot and a lot of gags, big-time laughs," director Peter Farrelly summed up the premise from the set.

So without further adieu, here are 25 things to know about what it took to bring all that lowbrow humor to the masses—and why the masses couldn't stop laughing:

"The thing that I like about it so much," Jeff Daniels said about the original film in 1994, "these are the jokes that everyone laughs at, but half the country refuses to admit that they do."
