I happened to watch an episode of David Letterman's show on TV and his guest is none other than the great comedian Jim Carrey. He is a Canadian born actor known for his roles in James Ventura, Mask, and other comedy films. He was there in that pop. show of David to promote his latest movie "Mr. Popper's Penguins." He was seen once again doing a hilarious stunt which didn't make David L. laugh because it turned out Jim's stunt was already seen before in his show when another great actor Tom Hanks did the same kind of pulling, rather fooling around. So the actor Jim Carrey was embarrassed and kept quiet for a while. That's was busted! Shameful. Then yesterday while I was watching the movie Dick and Jane, a movie of Jim Carrey and Tia wherein Jim had that same "stunt" he did at David Letterman's so which one is copying then or immitating a stunt? My God! I think the two actors are trying to audition for David L. then. Sort of. My opinion. There are 2 movies of Jennifer Aniston wherein same stunt was pulled over too. What's goin' on? Only the meticulous observers can view the difference anyway. How sharp your eyes are or vision or how sharp is your memory.
