This guy customer guest at work today was asking me to describe the different pizzas we sell. That's pretty normal; nobody ever knows what a margherita pizza is (whole tomato slices with parmesan and basil). But then:
Guest: "Ok, and what is pepperoni?"
Me: "It's just pepperoni and cheese."
G: "But what is it?"
M: "Um, it's pepperoni on top of cheese."
G: "But what is pepperoni?"
M: "It's... a kind of meat."
G: "Like beef, pork?"
M: "I... I don't know."
G: "Well... I'll have cheese then."
To Wikipedia! Hooray, my car is making funny noises! If it can't be fixed for less than the car is worth (hint: I have more than that in my wallet right now), my parents will buy me a new one!
