Brother going to prom

I just found out that my brother asked someone to prom and i said" i thought you were not going to prom." I just can't wait till he has to get all dressed up and go to a dance. I think he is going to look so funny and all my family is going to have to fix him up so he looks nice and find a car to use or ask my grandma if he can use her Camaro  witch would be so shocking because he is a country  boy and he has a truck. So who knows what he is going to do.
