Every Rosemary Has Its...?

[Warcrimes McGee]

In the quest High Stakes when you're tracking down the halfling who stole the gold, there's a part where you come across a crate dropped from his cart with a crossbow underneath. After a short conversation about it, Geralt says "There's a crossbow underneath. Heh. Tempted to make a pun about every rosemary having it's-" and then he gets cut off by the chick. So what's the pun? I can't figure out how rosemary could possibly be related to a crossbow. What was he going to say?

Crossbow - weapon with SHARP arrows
Rosemary - spicy herb (or SHARP in taste, or has sharp flavor)
The thief had a crossbow and there's the mark of the company that sells spices from Zerrikania - so the situation has taken a sharp turn

I think i that the pun is every rosemary has its thyme.
