The character "Tony Clifton" is almost certainly an allusion to the alter ego of comedian Andy Kaufman, who was very popular when this episode was filmed (though the Clifton character was much better known to those behind the scenes).
When Andrea is getting dressed, she closes her closet, and a poster is briefly glimpsed on the closet door. The image is a group photo of popular 80s band Duran Duran, specifically from the cover of the 1983 album "Seven and the Ragged Tiger".
