This is one of the most amazing Tonight Show interviews of all time. In December 1994, while promoting Dumb & Dumber, Jim Carrey completely took over The Tonight Show. In it, he "hypnotizes" the audience and makes them applause at will, explains how he was abducted by aliens and shows the "markings" on his abdomen by drawing on it with a marker, and finally sings "White Christmas" perfectly out of key. Amazing. Enjoy!
