While some famous people are able to keep in touch with reality and stay grounded in their roots, some people can make alarming transitions. It's hard to believe that the person screaming at a cocktail server for not remembering to give them five whiskey-spiked cherries for a scotch is the same kid who sat in a fifth grade classroom and struggled with algebra, but fame is complicated.
Most stories of celebrities before they became famous are just that they were otherwise pretty normal, quiet kids who had a hyper-focused talent or obsession. Sometimes though, your hairdresser's sister's uncle has a friend who was Paris Hilton's dog walker and the happy hour conversation gets a lot spicier. So, when a Reddit user asked, "Past teachers of present celebrities/famous people - what were they like?" people who shared a classroom with a famous person were ready to reveal the pre-fame gossip.
