Looks like security-centric ubergeek Bruce Schneier would give Chuck Norris a run for his money:

• There are no prime numbers, just numbers Bruce Schneier hasn’t bothered to factor yet.
• Bruce Schneier shaves with Occam’s razor.
• When he was three, Bruce Schneier built an Enigma machine out of Legos.
• When Bruce Schneier observes a quantum particle, it remains in the same state until he has finished observing it.

Some of these are too geeky for me, and I’ve read Cryptonomicon. To which Schneier contributed, natch.
