[Rosie the Original] I heard that in certain concentrations cyanide has a tang of garlic.

In any event: Women! Stop stinking out the house/windmill with your experiments in chemical weaponry!

[Stevie] Is food (and specifically patisserie) considered chemical weaponry now?

(the real Stevie, probably) I've never smelt it as garlic, always almonds. A bottle of potassium cyanide has got this smell due to hydrolysis. It's true that some smells can change with concentration. H₂S is bad eggs when dilute but The Full Monty is odourless and dangerously toxic.

[penelope] Weaponry for sure, and not just chemical! Haven't you heard of dwarven battle-bread? I think it highly likely that the late Sir Terry got the idea when he cut his lip open on a bit of stale baguette or something.
