Charlie Day was born on February 9, 1976. He attended Portsmouth Abbey School in Rhode Island and went to Merrimack College in Massachusetts. He played the role of Michael Boscorelli in NBC's Third Watch, a television drama about the adventures of firefighters and police officers in New York City. Charlie is now married to Mary Elizabeth Ellis, his co-star in the FX sitcom It's Always Sunny in Philadelphia, where he is also an executive producer and a writer, along with Rob McElhenney. Charlie Kelly can be regarded as the loser among his working companions in Paddy's Pub, where he is a co-owner. He is poor, a potential dyslexic, and considerably slow when it comes to learning. He is assigned to do the most disgusting tasks at the bar. Eventually, he will share his sofa-bed with Frank Reynolds, a divorced, middle-aged guy who bought a share of Paddy's.
