While Steve is away, Marcy borrows his new Mercedes and prangs it on a fire hydrant. When Steve finds out, it affects his performance in the bedroom. Desperate, Marcy goes to Al for help, who tells her that to rectify the problem she must become more servile. This works but, in an amusing twist, we learn that the whole thing was a scam dreamt up by Al to enable Steve to control his wife.
The revelation at the end is funny but also proves that Steve is little better than his neighbour when it comes to dealing with the opposite sex. A dent in a fender can easily be fixed, but a dent in a relationship is harder to mend. Steve and Marcy's marriage ultimately fails, as we find out in a later season: the writing is already on the wall in this episode...
