The Concept of Bottomless

I told my father that we should get a hamburger so that we could get bottomless fries. He asked me why it was called bottomless fries; the syntax didn't make sense to him. I told him that it was because the fries were bottomless and would never end. We demolished the first plastic tray sparsely filled with fries, and my father said that it should be "free fries refill on request."

And then he said "Oh look, it's Santa!" with gusto as a particularly rotund man with white hair and bears and a red t-shirt that failed to hide his rotundness walked by. Luckily, he said it in Cantonese.
