He goes so far as to personally return the favor to a neighbor who allows his Great Dane to leave droppings in Charlie's yard. It also happens to be funnier. The Farrellys leap into the area of bad taste with single-minded gusto. Unfortunately, they're so busy crafting jokes about Hank's peculiar tastes that they let the plotting of this film slide. Once Hank's background is established, the story actually begins.
Trouble follows the pair and they wind up on the run from crooked cops.
They're in such a hurry that Charlie forgets his medication and finds himself changing unexpectedly into Hank and, just as suddenly, back to Charlie again. And both of them fall in love with Irene. The road-movie format allows the Farrellys to drop in non sequitur sequences that allow Carrey to act out. There are so many such pieces that the film stretches to almost two hours, when a little trimming would have pushed the laughs closer together. Carrey may be our most inventive comic actor.
