Okay, this link is too good to pass up:
... it's kind of like this one, but not:
I really must rethink my ban on television watching (22 years and counting), these were really edifying clips.
In a totally-related link (related by Chaos), it is found that Ninjas are mathematicians in this blog entry.
Makes perfect sense to me: after all, I'm a Ninja and mathmetician (don't quite remember my Erdos number right now (nor, embarrassingly, my Shusaku number, as I didn't even know this number existed until just now ... oh, the things one finds when one looks ...), so please don't ask), so, via generalization by sophistry, Every Ninja is a Mathmetician, Q.E.D. Do not read in that blog the comment posted by this weirdo geophf person, unless you're open to having your brain melt.
