Sounds like this kid was at the 'my game is better than your game' stage. I had a similar conversation one day that went a little like this:
(We'd established that we both played DnD, which was a cinch since I was reading the BoVD while having coffee at the store)
Kid: What character do you play?
Me: Usually, I DM. But I played a Paladin for a long time and I've got a Mystic Theurge in another campaign.
Kid: What level?
Me: The Paladin's 20th, my Mystic Theurge's 9th.
Kid: I play a 30th level Necromancer and it's really cool 'cause I've turned the rest of my party into Vampires. And I created a spell that kills Ancient Red Dragons in one hit.
Me: -containing myself admirably- What level did you start at?
Kid: -looks up to his left- 1st.
Me: And how long did that take you?
Kid: Three weeks.
Me: You're fibbing, aren't you?
Kid: -squirms, looking guilty, then walks away-
