In the season 1 episode "Lover's Lane" the Conners, Jackie and Crystal go out for a night of bowling. In one scene Crystal asks Dan what size he takes in shoes and he replies an 11. Okay, ten episodes later in "Mall Story", the Conners, Jackie and Crystal are on another outing, this time at the mall. Here's the slip up...Roseanne persists Dan to pick up a new pair of shoes, and when he asks the shoe salesman for help, he asks him to bring him a size 13D. Now, correct me if I'm wrong, feet do not grow two sizes in what is obviously a few weeks/months, especially for a full grown man.
