How Many Holes Does a Straw Have?
I was recently listening to an episode of The Rest Is Science, specifically the episode The Evolution Of The Butthole. As always, Hannah and Michael put on a great show and I came away thinking about its contents.
In it, they asked how many holes does a straw have? And my default response was something like:
Why they have 2 holes, silly! One at each end.
You probably don't need it, dear reader, but here's a handy-dandy diagram of what I'm talking about...2 holes, right?

Then Michael asked "okay, how many holes does a doughnut have?"
Bah! More simple questions! A doughnut obviously has 1 hole, right? RIGHT?!
Here's another diagram (look, I know you're a clever person, and you don't need a diagram of a bloody straw, or a doughnut, but we're going with it, okay).

We're all on the same page here, right folks? A straw clearly has 2 holes, and a doughnut obviously has 1.
This is where it gets interesting. Michael now flips script, and quite frankly, blows my fucking mind. He said:
But isn't a straw just an elongated doughnut?
What. The. Actual. Fuck?
A straw is just an elongated doughnut (albeit not as tasty). So does a straw have 1 hole? Does a doughnut have 2 holes? I don't know. I'm questioning my life decisions at this point. It's all too hard.
Can any of you tell me how many holes a straw (or a doughnut) has?
