I wish people would stop thinking Oscar is Venkman’s son. It’s IMPOSSIBLE. He hadn’t seen Dana for years and he met him as a BABY!!

Bill Murphy knew how to court a lady.
Of course…
it was a rumored plot point when Murray was still believed to jump on the GB3 vagon.
Oscar never was, never is, never will be Venkman’s son.
Not biologically, no. They could write it that Venkman and Dana got married (they could say “back in 1992” to avoid contradicting the Video Game :roll: ) and Venkman’s basically raised Oscar his whole life. I’d call that being Oscar’s 'real father"; he’ll just never be his “sperm donor”
Of course, if Murray isn’t involved with GB3, and GB3 never gets made, it’s probably all moot anyway.
