White Poop?

Yes, a interesting title right?  It's amazing once you have kids how poop talk becomes a regular topic.  Anyway, my sister was on a business trip and I was watching Kaitlyn.  Ryan came to pick her up and I was running through her schedule that day, including potty trips.  Emily overheard and said 'yah she was in the bathroom a long time pooping'.  I told her that's o.k. everyone is different and everyone poops.  To which Ryan chimes in 'even Santa Clause'.  It was quiet for a moment and then Emily asks 'does Santa poop white?'
