My 9 yr old grandson. Put a lot of sticky tabs all over my car one nite so I played a joke on him I open a pack of Oreo cookies I took the cream filling out of a few cookies and put toothpaste then I put the cookies back in the pack sealed it shut... The next day I asked him did you eat your cookies he said yes thank you mommom after a few minutes I asked did you eat all of them he said yes ..... REALLY he ate all the cookies even the one's with toothpaste and he told me they we're good i think my joke failed
