You’re not missing much. I mean, it’s a 20 year gap in their careers. There’s a gag earlier in the film where Daniels visits Carrey in a nursing home because he’s fallen into a coma for 20 years and then Carrey finally “wakes up” and says it was all a gag. It’s almost like a nod to the Andy Kaufman conspiracy theory that he was faking his death as part of an elaborate real life bit.
