From Legacy Wiki
The Holy Toothbrush comes from Gangsterz 2 - Version 1. Back when staff were allowed to play the game and had quite normal profiles, the Holy Toothbrush was a special item Zorg wielded. It did 0 damage and had 0 accuracy, so it was mostly for comic value. The toothbrush was later stolen by Steve, before the game eventually shutdown. On Christmas 2008 Zorg put an advent calender up and on the 13th you got a .. TOOTHBRUSH!
This time it came with 1-2 damage and 1 accuracy.
