When Vince Vaughn started out his acting career, the best work he could find was mostly in cheesy afterschool specials as he’s got no less than four of them listed in his early filmography! One of them was this 1990 episode of ABC Afterschool Special entitled A Question About Sex starring Tracey Gold of Growing Pains fame and Ferris Bueller’s mom as a mother-daughter duo who are constantly fighting about whether or not sex ed should be taught in high school. Vince Vaughn’s role here is very small, but you can see him at the 1:18 mark of this clip.
