What they would do.

John: *would end up breaking the bands off.*

Paul: *would complain constantly because he thinks they reduce his beauty.*

George: *would get irritated that he's not supposed to eat certain foods but just eats them anyway.*

Ringo: *would freak out when he can't get the food out of them.*

What they would say.

John: These things are stupid. I don't need them. My teeth are fine the way they are! *crunch.* Oh, look a band fell off. Oh, well.

Paul: *dramatically.* Why???? Why do I have to wear them? They make me hideous!!! My beautiful smile is ruined! Ruined, I tell you! Soiled it! Soiled it! Soiled it!

George: I'm not supposed to have popcorn. Ha! That's funny! *shovels popcorn in his mouth.* I'm supposed to have taffy either. What a riot! *scarfs down some LaffyTaffy.*

Ringo: I've got something stuck in my braces. *picks at it for the next ten minutes.* God, it's still in there! *struggles for five more minutes.* I'm going to go insane!!! *starts sobbing.*
