To be fair, Grease is a parody, and that was part of what they were parodying at the time. So they went a little extra with it too.

It’s a parody of the super common “beach fling” style of movies from the 60’s. They even reference some common actors and actresses from those movies.

It’s why each scene seems so poorly tied together, and the characters aren’t very consistent.

I was able to grow a full beard in 10th grade so this isn’t that unrealistic.
