although , trivia might not be the right word
I'm not even sure how many people have actually watched Grease 2 , although , I liked some of the some , the movie it's self is tough to watch , I don't think I've actually seen the whole thing
but in Grease 2 , there are two twin sorority girls , those two twins are Jean and Liz Segal , the younger sisters of Katey Sagal , AKA Peggy Bundy from Married With Children
they even had their own short lived TV show in the 80's , although I don't remember it , but I was in the Navy at the time , and missed alot of short lived TV shows
not sure how I ,missed this one though..................lol
