There is nothing better to solve a social problem than the implementation of....KEG RACES!!!!!
Of course I'm kidding
Um, how about you remind them to get off their bon bon eating behinds and get to work to raise some $$$ for charity and kids?
For crying out loud, it's for charity!
The best way to get people to come is to advertise. Get some fliers made up advertising that the sorority will be there, in bikinis! Go around and put them on all the cars on your campus.
Just one question though, do you think the girls may be a little hesitant because it's still WINTER?!
