One Of These Things Is Not Like The Others

Let's take a close look at the following items and see which one doesn't belong in the grouping....

GUN. Obviously = weapon.

HAND GRENADE. Obviously = weapon.

KNIFE. Obviously = weapon.

CROCHET HOOKS = NOT a weapon!

Can you believe my crochet hook was almost confiscated at the concert yesterday?!? Um, exactly what harm am I going to cause with my hook? Am I going to quickly crochet a blindfold around someone's eyes and then trip them? Because even I don't crochet that fast. Stupid security officers (and HA HA, I smuggled it into the venue in my shoe. TAKE THAT, bullies!).
