When I only had one early class. He would normally set up on the library lawn and yell at all us sinners.
Things I did to him
After being told that looking at women with lust in your heart turns them into whores, I turned to an attractive woman and said, "I would very much like to apologize from the bottom..." As I faded out, I pretended to be mesmerized by her chest before snapping back. "Oh, yes... Where was I?" Preacher called me a whoremonger.
Once while walking about half a football field length from him, I gave my backpack to a friend walking with me. I then struck a dramatic pose and yelled, "EVANGELIST!" to get him to turn around and look at me. When he did, I start running as fast as I could while screaming, "AAAAAAAAAAHHHHHHHHH!" He jumped into the crowd to get away.
Once while going on about the evils of music and dancing, I saw a Latina friend of mine walking to class. I called her over and asked her to walk me through a salsa step she was trying to teach me. So we started dancing in front of the guy, and he started yelling at us. My friend was confused at first then caught on and enjoyed the joke and even yelled at him for a while.
And best of all, due to repeatedly yelling a catchphrase of, "Tell us about the gay monkeys, damn it!" at him, I became known as Gay Monkey Man (it involved wanting him to explain why there's homosexuality in other animals if they don't have souls - he had no good answer). Years later I was the 4th person to arrive at a lecture being given by James Randi. He was setting up, and there were a man and a woman already in the room who looked at me strangely and then asked, "This might sound crazy, but... are you Gay Monkey Man?" That got a quizzical look from Randi, and I said, "It involves mocking a street preacher who didn't like homosexuals very much," which then got a smile from him. That made me happy.
I looked at the online version of the campus newspaper once and saw that after I had left, a grad student had taken to dressing like a wizard and competing against him when he came to preach, claiming he wanted to save student souls and validate their parking.
