Grandboy (breathing hard after performing a one-man show of the equivalent of WWF performed by ninjas on roller blades on my bed): …so now I’ve increased my fighting level to an UNBEATABLE LEVEL.

Me (reading a Terry Pratchett novel): An unbeatable level?

Grandboy: Yah! Like INFINITY OR EVEN MORE

Me: …

Grandboy: O no I can’t be INFINITY LEVEL that’s the strongest thing in the UNIVERSE. What is the next strongest level to infinity, grandpa?

Me: Infinity minus one.

Grandboy: A yes that’s the level I’m at now (tosses himself in the air on his back). Aaaaand ding ding ding now it’s time for the CHALLENGER
