Me: Okay, so we're going to study elimination today. *Go over basic method*
Student: Whoa, that's easy.
Me: Not so fast, there are a few monkey wrenches coming.
Student: How many monkey wrenches?
Me: 3
Student: Do they get harder as we go?
Me: Yeah, they generally do.
Student: So it's not just 3 monkeys, it's more like, "Spider monkey", "Orangutan", and "King Kong"?
