The Dumber clip is out for the world to see.
Jim Carrey and Jeff Daniels unveiled the new trailer for Dumb and Dumber To on The Tonight Show Tuesday night.
Carrey and Daniels are reprising their roles as the moronic screen duo from 1994's Dumb and Dumber.
Peter and Bobby Farrelly have reunited to direct the sequel project due out November 14.
It's been so long since the original comedy that Carrey insisted on having a Tonight Show couch for his evening interview.
"I'm 50, I nap," said Carrey, 52, pretending to fall asleep mid-interview.
The comedy begins with Carrey's character, Lloyd Christmas, in an asylum visited by Daniels' Harry Dunne.
In no time, Christmas goes from long-haired and bearded to his familiar bowl-cut hair creation as the two set off on a crude adventure looking for Dunne's lost daughter.
"It's not even a movie anymore," said Carrey. "It's a phenomenon."
