how old was he?

cartoons in canada are pretty silly

I don't know.. 40-something?

The conversation was something like:

Guy: Prof, do you have the power of the ninjas?

Professor: *stares silently* ... I don't think we watch the same cartoons.

He was awesome.

He would write down a quadratic equation, look at it for a couple of seconds and say "Well, it's clear that the solutions are 16/19 and 5/9".
