Super Dick!!!
A super hero dick would be pretty awesome. The only negative to it is if John hates his arm when it leaves him, wouldn't it be annoying if he was having sex and his dick had to go off and save the world? That would be really annoying. Unless he had two dicks, but I don't want to imagine that. You also get bonus for using Frankenstein, the best psychedelic instrumental rock solo next to Echoes!
Now to the fourth (I'm adding the first three to my favs.)
