OMG these are hilarious.
I have another that one of you reminded me of.
When DD was about 4 we were in the grocery store and in the line in front of us was a woman with bright pink hair. I did my best to stay between her and DD so that I would not get the all too familiar, "HEY MOM" Well I failed miserably because very soon I heard, "HEY MOM, WHY IS THAT LADY'S HAIR PINK?!?!" The lady just turned around with a very smug smile and looked at me waiting for me to answer this loud child. I looked at DD and said, "well honey her hair is pink because she chewed too much bubble gum as a child." Pink lady thought that was great.
