- I got this new quantum computer yesterday.
- Cool. How is it?
- It's alright, but it's a pain to program.
- Why?
- Because all my boolean evaluations always turn out both true and false, at the same time.
- That must complicate things.
- Yes. My if clauses always get executed, as well as the else clauses. But at the same time, they're not executed at all.
- Tough.
- Yeah, and as if that wasn't enough, the programs always calculate all values that are possible to compute. I'm going nuts about it.
- So why don't you throw it away?
- I tried, but it turned out that I both threw it away and kept it.
- Oh.
