Pirate

I'll admit Worms is extraordinarily fun and creative, but best weapons ever? I dunno. I just didn't get the "Wow" factor from them. Fun and clever game, though, for anyone who has never played it. Out of the worms weapons, I'd say the "Holy Hand Grenade" is most funny and "mad cow" is most bizarre. "Prod" is great because it is so understated, but the one awesome weapon that you just love when it appears is "Airstrike".
