Run the Race With Endurance (and bring some towels)

This is one for the books.  This is one that he will hear about until his kids start telling the story to their kids. A couple weeks ago, Walter and I were in the kitchen and the kids were playing upstairs. I think Walter was making tacos and I was cleaning up.  We were engaged in the normal how-was-your-day conversation and every once in a while one of the kids would appear between our feet and we'd shoo them to the other side of the counter.
At one point, I paused and noticed that the watermelon I had sitting on my counter was in the living room.  "What is my watermelon doing in the living room?" I asked the kids.  "It wasn't me!" the both replied. "Bring it back in here on the counter," I said and went back to my conversation with Walter.  We were solving the world's problems and talking about geeky stuff or something when, from the corner of my eye, I saw a dark red cherry slushie oozing down the bottom few stairs. "That can't be a cherry shlushie.  Where did they get a slushie from?"  And when I rounded the corner, I wittnessed the true enormity of which the cherry slushie-ness was just a tiny piece.  Because it wasn't a cherry slushie that had gone down my stairs (thank goodness!).
But it was the whole entire over-ripe watermelon that had taken a bouncing trip down the stairs.
About half way down, it had busted partially open and splayed its frothy red guts on each subsequent stair, then exploded on the tile at the bottom, and then whooshed back up the oppisite wall.
Time froze. Nothing in our house moved. Everyone stood as statues with mouths agape. Surely, my wonderful well-behaved children wouldn't even think to do something like roll a whole watermelon down the stairs. Surely they wouldn't.  Would they?
And then someone hit the play button and we unfroze.  "WHAT ON EARTH WERE YOU THINKING!!" I asked Roman who was now on the bottom stair.  "Chloe told me to do it!" he said.
I had a passing thought to grab my camera because words could do the scene no justice. But Walter and I snapped into action with towels and carpet spray and more towels so that the goo wouldn't stain the walls and carpet.  He managed to scrub the carpet so that the pink tinge isn't visible, but if you look at the bottom wall in just the right light from just the right angle, you can see a faint something-different about that area.
