When Roseanne & Jackie talk about Arnie, they act like they haven't known him long. Jackie even states, "I don't know him." Yet, in episode "Why Jackie Becomes A Trucker," Jackie sleeps with Arnie. Roseanne says all the girls made a pact in high school that none of them would ever sleep with him.
Roseanne's three ex-husbands have appeared or worked on the show during its run. Her first husband, Bill Pentland, wrote a few episodes for the show and played Dan's friend, Freddy, in a season one episode. Tom Arnold, her second husband, played Arnie and was an executive producer. Finally, her third husband, Ben Thomas, had a cameo as a police officer who pulled her and Jackie over in an episode later in the show's run.
