Shopping with a 4 yr old.

We went to Walmart yesterday to pick up some spring/summer PJ's for Jake. While we were there, I decided to look around the women's lingerie and see if I can find a new white bra. Jake takes one look and the wall of bras and loudly exclaimes
"But MOM, you already got those!"
"Yes, but I need another one"
"Another one? but you already gots those"
"I know"
"But who's these for?"
"For Mommies"
"Mommies like you?"
"just like me"

And on it goes....
