Harry offers to sell Tim 20 percent of his hardware store (that Harry's brother is selling). Jill doesn't let Tim buy it, so Al decides to purchase it. When Al becomes obsessed with the store, this drives everyone crazy, even Ilene when he skips a date with her, and Tim decides to confront him about it. Brad and Randy try to beat Mark, as Al in a Halloween costume contest, but Mark wins because Al's mom was the head judge. (thetvdb.com)
