Can you provide a list of petty insults?

I need some petty insults for a project on self esteem. Ones that tweens often use, like "Nice glasses, NOT!" Stupid stuff, like that. I don't wan't bogus answers like "You're so dumb that you're dumb." or yo-mama jokes. Things that kids would use to try and hurt. Here's some more examples:

"Nice iPod, what is it, a first generation?"

"Wow, my little sister has that exact same shirt!"

"Oh, so you've still got the same backpack as last year?"

"Nice zit!"

"Nice highwaters!"

"Oh, your nailpolish matches (insert disagreeable object's color here)"

Those were all I could think of, and they're mostly about possesions. The answers could be about anything though.
