The setting: A conference meeting in Zurich on computational models in astrophysics. It's the end of the third day and the discussion section on the presented talks has just started.

Chair: So today's results can be summed up as "Your simulations suck!".

Audience member: Don't you mean, "Our simulations suck!"?

Chair: No, no, I mean your simulations suck!

Audience member: Okay. Just so long as we clarify that.

And so begins a debate on one of the oldest topics in the world; are girls really better than boys? Oh, wait, no, I mean the other longest debate... particle codes or grid codes?

[An hour later]

Chair: So what we're really saying is it's all the observers' fault?

[Mass cheering]
