I know it's a musty old joke, but now seems like a good time for it. Why don't Baptists believe in pre-marital sex? Answer: It might lead to dancing:
The first on-campus dance ever allowed at Anderson University attracted several hundred students over the weekend, although they mostly stood around and danced in large groups.
The university, which was founded in 1917 and is affiliated with the Church of God, had prohibited dancing until the school's trustees approved a policy change last fall.
