NONE of my old tricks worked.
So I busted out "Sexy and I Know It" on my phone to let them dance it out. (Thank you after school program for letting my kids hear wildly inappropriate top 40 hits, now I can listen to my music with them!)
Then I promised to pee on the flowers when I counted to three. People, THIS IS HOW YOU DO IT.
I knew that was a winner so we called it a day. They got their ice cream and some dandelion action as well.
