Everything.
It's a lot. There is fruit, vegetables, accents, stirrups, Saran Wrap and who knows how much more. Sometimes, I think maybe there's TOO much. But no. Isn't a comedy always better when you don't catch everything the first time? Sure. Life's a comedy, obviously, and there are lots of amusing bits.
Why so much, though? Really, it's mostly space fillers. Water is simply a space filler in between fish. It's simply a matter of sorting the worthwhile from the useless. Take tennis: one hits the ball, not the air or the net. You go hit that ball. Meet you here.
