Sounds pretty cliche and unoriginal anyway....
Wow you guys are rude. This guy is planing to ask one of the most scariest/nervous questions in his entire life and you act like that. I didn't think I would be nervous when I asked my wife in her hand in marriage but I was so nervous that I drank her two glasses of wine and my two glasses, took 2 potty breaks within 2-3 minutes before asking and also ate her salad......and I hate salads.
Good luck on the proposal but just make sure she'll like the proposal and that its not going to embarrass her. Girls are always dreaming about the perfect proposal. Lets hope that if you do it at Memorial Stadium at a game that it doesn't end up like this guy.......
