Chelsea Handler went on the "Tonight Show" last night and showed video of an elaborate prank she pulled on her older boyfriend in preparation for her appearance. She took him over to her agent's house and gave the agent's dog, Dudley, crab meat. Handler then pretended to get a call from the agent saying that Dudley had died. Chelsea proceeded to convince her man it was her fault and then say they had to attend the dog's funeral. She caught the rest on candid camera.
