Oh dear dear dear dear I must protest!
According to Jellyface, my three year old son and professional puddle jumper, to properly jump in a puddle:
1) Wait until you have been changed into your best outfit for Uncle Jake's Bar Mitzvah/ Auntie Sparkleface's Wedding/ Grampa Dale's Funeral.
2) Find any puddle. If none are available, one is easily made by emptying a cup of juice in the dirt. If no juice is available then milk. If no milk then pee.
3) Jump jump jump jump jump all the while singing "The Ants Go Marching One By One Hurrah, Hurrah!" at the top of your lungs.
4) If you see an adult approaching, run and giggle till you are caught, then cry.
