David Spade and John Pinette were real stand-up comics. This aired 3 months prior to Spade's first episode of Saturday Night Live (1975).
Spade joked on his podcast Fly on the Wall with Dana Carvey and David Spade (2022) that he did not include ALF (1986) on his resume.
Brandon Tartikoff appeared as a character (played by actor David Leisure) in the second season entry "Prime Time."
Lynn and Brian only appear in ALF's dream.
John Pinette uses the character name Howie Anderson which is a combination of two other stand up comics, Howie Mandel and Harry Anderson.
