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.
