Take three bored and whiney children. (in an appallingly unkempt yard might I add). Add one water hose on the slide, and one kiddie pool below and POOF! Now you have loud, noisy, happy children in a ghetto water slide.
Edited for Update: So I start hearing these chants "mud, mud, mud pit". So I go outside and the children are recreating the mud people from woodstock... so the showers commenced. Why no pictures you ask? Well, its funny now, but wasn't so funny then.
