Funny Mommy

We were eating dinner tonight, hamburgers...grilled out (because I know you care). Zac looks at me and says,

"Mommy, you're funny."
Me: "Oh, I am?"
Zac: "Yeah... You're funny when you're stupid."


Fact: Usually, I correct my children when they say the word stupid...but in this case, I couldn't discipline because I was laughing too hard. What can I say?? Maybe I'll correct next time...
