This is a gross question, so if you’re bored by such stuff or easily offended, better stop reading now.

I ate a small bowl of corn on Saturday. Then on Sunday I ate a large bowl of Grape Nuts.

So Monday morning, the Grape Nuts come out. Then Monday evening, the corn came out.

How did the Grape Nuts pass the corn in my body? Where did the corn go, while the Grape Nuts sped past it on the way down?
