Recent Examples of My Razor Sharp Brain

These 8 year olds try it on don't they? But mine's no match for my sizzling brain, as you'll see:
Me: - Don't walk directly behind me. I can't see you.
8y/o - I thought you had eyes in the back of your head.
Me: - I've got a hat on though haven't I?
8y/o - I think my DS is broken.
Me: - Oh no, we'll have to be quick and send it back.
8y/o -  How can we send it back to Santa?
Me - Oh, the elves don't make the really technical gadgets. Santa gets them from the manufacturers just in case they go wrong.
(Phew.)
No flies on me!
