I'll have to go with you on this one. I'm not really sure why your wife would object to it. I don't know what else one would say to a 6 year old. And, in your case, it's good you didn't say "Want some candy, little boy".
Also, while I'm at it, HAHAHAHAHHAAHAHAHAHHHAHHHAA at Vick's concussion. I think I warned you of such things.
