Born on January 26 in New York. He attended American University (History major thank you very much) before pursuing his comedy career. After trying his hand at stand-up, Callen made his TV debut as a series regular on Mad TV, which also served as his breakthrough. (I think bios are cheesy) Like anyone cares when I had my "breakthrough". Yeah after MADTV I went on to do OZ, INSIDE SCHWARTZ, 7th HEAVEN, FAT ACTRESS and countless other sitcoms and episodic crap. Impressed yet? Yeah like the world would be different if I was hit by a truck tomorrow. LA is way to self involved and for that matter so is everyone now adays. People need to open a newspaper and a history book once in a while or every day to get some perspective. That's my bio. I'll keep you posted on when my next show comes. Everytime I book a new TV show the first thing I think of is, hmmm now I get to eat out a lot, buy cool stuff and date hot girls. Is that bad? I'm shallow as hell but at least I'm trying to swim to the deep end. PS I just watched some of my old episodes of MAD TV and I find my high voice and 150 lb frame embarrassing. At least I'm 25 lbs heavier and I've taken some voice lessons. Now all I need is a hair transplant (I want that long black Johnny Depp hair please) and a little human growth hormone. (makes the skin healthier and puts on about 20lbs of muscle).
