The episode is notable for having the first Rob and Laura duet; a song and dance of "You Wonderful You".
Continuity issues: Sol Pomeroy is played by Marty Ingels. Later in the series, Rob is shown to have had an Army buddy named Sam Pomerantz. Possibly he did have two friends, Sol Pomeroy and Sam Pomerantz. In any case, however, there were three different actors playing Army buddies with some variation of the names.
Also, Laura's last name in this episode is Meeker -- later changed, in other episodes, to Meeghan.
