Need Fundraiser event ideas?

I’m on a committee for my office in which we plan 2 weeks of fundraising events to benefit local charities every year. We are always looking for new and fun events that can be done (preferably with low cost to the company). In the past we have done lunches such as tacos or potato bar; Jail lock in – where secretaries and staff must be bailed out by the boss if they want them to work; Auctions – silent and live; karaoke party; mini golf tournament around the office, etc…

Does anyone have any fun event ideas that would produce profits and be fun for everyone???
