"What do ya mean, funny? Let me understand this 'cause, I don't know, maybe it's me, I'm a little fucked up maybe, but I'm funny how? I mean, funny like I'm a clown, I amuse you? I make you laugh... I'm here to fuckin' amuse you? What do you mean funny, funny how? How am I funny? What the fuck is so funny about me? Tell me."
Tommy DeVito (played by the man himself), Goodfellas.

Joseph Frank "Joe" Pesci (born February 9, 1943) is an American actor, comedian, singer, and musician. Usually known for playing violent mafia mobsters or grouchy but lovable funnymen, Pesci has starred in a number of high profile films such as Goodfellas, Raging Bull, Once Upon a Time in America, My Cousin Vinny, JFK, Home Alone, Home Alone 2: Lost in New York, Lethal Weapon 2, Lethal Weapon 3, Lethal Weapon 4 and Casino. He has proven himself very adept at both raw drama (Goodfellas, Casino) and comedy (My Cousin Vinny, Home Alone).

He is famous for portraying characters with terrifying Hair Trigger Tempers. He has a really filthy mouth. note 

He was also a good friend of stand-up comedian George Carlin, who said in his routines that he prayed to Pesci, because he "looks like a guy who can get things done."

Despite playing dangerous sociopaths, he is known as an extremely humble, soft spoken man who gave one of the shortest speeches in Oscar history after winning Best Supporting Actor for Goodfellas. He simply took a breath and said "It was my privilege. Thank you." It was over in three seconds. The reason for the brevity is that he really didn't think he would win and didn't prepare a speech; he was genuinely surprised.
