HELP! My school's senior T-shirt design was very lame and more then half the class thinks they're awful. I want to make new ones for all the kids.

So pretty much my school doesn't let kids help in design processes, no one liked the turn out and the school didn't care. So I want to make new shirts and have them printed. Since they aren't being sold by the school I have the freedom to do basically whatever I want with the design since I'm doing this on my own being. However I can't really think of anything creative & that people will really like.

Here is how they came out: http://i.imgur.com/sjPxi.jpg

Some stuffs:

*School logo is a Black Knight

*School colors are Black & Gold

*School is Lake Lehman

The SENIO12S was stolen from the glass of 2010' who used SEN1ORS which I thought was cool but continuing the graduation year in replace for IR for 3 years now is like beating a dead horse. Also how unoriginal is 'Go Home Freshman!' - really lame. So Is there anyone who thinks they have a cool idea? Let me know!
