On second though...don't ever let your phone ring in class. I don't want to be a part of interrupting class.
And honestly, my advice is to just be yourself when meeting new people at Purdue. I think the ringtone of a clip may not be the best thing. May not be interpreted the way you want. I'd stick to being yourself and just talking aviation with your classmates. Never failed for me. I just thing that people may not be overly impressed with the idea.
Nolan does know about the site though, so let him know that you know, and that you talked to me (Matt). He'll know who I am. He'll probably tell everyone in AT100 about the site anyway, so they'll be exposed to the clips that way.
