What are some things your MCs say? Jokes, facts, etc.

Also something interesting, how about some new things for our MCs to say? After watching Mark Leon (#1 MC ever) at 3 regionals, I found he often says the same thing, over and over again, and this sounds like it happens with other MCs.

To start: Mark Leon's motto is "Do the math, save the world".

He enjoys math jokes.
