What are some good Student Council fundraisers?

Some good fundraising ideas could include things like: a bake sale where students bring in desserts to sell, a car wash, hold in-school sports games where teams can sign up and pay to play, and those who don't play, simply pay to get out of an hour of class or so, and other ideas along these lines. You could also have sports days, do something funny for money (Like Red Nose Day), Sponsored silence or fasting (Gets you dead hungry though) and last but not least a car boot sale in your school where you have to pay to have a stall.
