Classmates keep insulting me...26, law school?

I don't know what to do anymore. Im 26. The average person in my law school is 23. Someone asked about what nationality I was in my ethics class and I told them American. They asked then where my family came from originally before America and I said Germany. They have taken a liking to saluting me as if I were a Nazi. I don't want to be a baby but it has been going on for 2 months and it is getting old. THe more they know it bothers me, the more they like doing it but if I dont say anything, it gets even worse. What do I do?

You need to fight fire with fire, start picking on them for the same type things. I mean you are in law school, obviously you are not slow-witted or something. Sharpen your wit to a razor sharp edge at the others' expense.
Reply:Act like you don't care. They'll eventually get tired of it if they think it doesn't bother you.
Reply:You should study your butt off and get better grades than all them!! Then when you have the best grades salute them, they wont know what to do! ZING HIIII
Reply:That just shows the maturity level of some people- we all know that. I'd say to salute them back. Maybe if you join in the joke they won't think it's so funny. Lol. I'd be a **** and wear a fake mustache to class, but that's just how I roll. Don't let it bother you too much- In the end of it all, they aren't the ones who make you who you are.
