Leslie Baum was a character who appeared in the Season 9 episode of Married... with Children titled "Shoeless Al". The part of Leslie is played by Charlie Dell, who also played the part of Roy in "Poppy's by the Tree" back in Season 2.
In the episode "Shoeless Al", Al attempted to fake a stress disorder to sue the mall; Leslie was hired to prove Al was faking. At first he was unsuccessful, but then Al had to give up the lawsuit so he and his friends could win the bowling tournament (Al had to wear bowling shoes). This is the only appearance of Leslie. Leslie is a guy (something Al ridiculed, the name being, in his opinion, a female one).
