You never know when you might run across a vorpal bunny in your daily travels. It has decapitated many a man who has tried to cross it. The only Weapon known to be effective against the vorpal bunny is The Holy Hand Grenade of Antioch.

Fortunately for us, ThinkGeek offers the Holy Hand Grenade Danglers. They are meant to dangle from your rear-view mirror. While these are soft grenades and aren't likely to explode when you throw them, perhaps the mere sight of these grenades will be enough to keep the vorpal bunny away from you.
