Jim Carrey has plenty of trademark characters to trot out -- Ace Ventura, the Cable Guy, Fire Marshall Bill, the Riddler (wait, scratch that one) -- but the funny man seems to be quite recently endeared to a new, highly specific one: fellow actor Matthew McConaughey in his Lincoln commercials. Carrey debuted his take on the admittedly overly dreamy commercials during last week's 'Saturday Night Live,' but he's not done with it just yet.

On last night's 'Late Show,' host David Letterman barely had to ask Carrey about the impression before he broke into it. It seems like second nature now, very cool, going forward to go back, Lincoln...fun car commercial, guys!
