There is a scene in which Jackie and Donna are hanging out in the Forman living room, even though none of the boys are there. This was necessary because the set areas which normally housed the basement set and the Pinciotti kitchen or living room sets were being used for Bud's apartment and the bar.
The names of the firemen that Jackie hits on in the bar (Rob and Dean) are most likely named after "That '70s Show" writers Rob des Hotel and Dean Batali.
Both firemen in this episode played a boyfriend of Phoebe in the television show "Friends (1994)", and one of them even played a fireman.
