A childhood belief about general

I once made sandwichs for my dad and his friend. After I gave the sandwiches I went inside for a bit and then came back out, and noticed that while my dad was still eating, his friend wasn't. I asked where his sandwich was, and my dad told me that he just ate it whole, so he ate it faster, "without chewing?" I asked, and my dad said yes. I then could do nothing but picture a whole sandwich, floating in his stomach, and whenever I saw his friend after that, I always thought that the sandwich was still in his stomach, whole!
