I heard that, early on in Prince's studying with JWs, Larry Graham told him he needed to be baptized in the waters of Lake Minnetonka. So he took him to a body of water and Prince was there dunked--even though it was an icy cold March morning. Afterward Larry told the shivering Purple One, "Sorry. That wasn't Lake Minnetonka!"
Just kidding... But it would have been a nice payback for his doing the same thing to Apollonia! (The above was taken from a scene in Prince's motion picture, "Purple Rain.") Sorry, I'm tired and getting punchy...
