Met the guy here in Dublin...
I even have a signed copy of his Hyperspace book... when a famous physicist is being ushered around after giving a lecture the semi-professional monster hunter always gets introduced.
My copy of Hyperspace reads: "Luke, good luck in any dimension... -Michio Kaku"
I've also had conversations with the guy who won the Nobel prize for creating a Bose-Einstein condensate, and one of the dudes who cloned Dolly the sheep.
Seems if you're doing the lecture circuit you just get bored braindead answering the same questions over and over again... suddenly the chance to speak with an amateur treasure/monster hunter can pique any skeptics interest.
