In the right hands, practically anything can be an effective weapon. For proof of that, check out this security footage from an Ontario cannabis dispensary last Thursday, which shows two workers restocking shelves and minding the counter when, suddenly, the store was attacked by four male assailants brandishing bear spray.  

Thinking fast, the store clerk grabbed the closest blunt object he could find - a glass bong.

Seeing that he meant business, the attackers quickly lost their nerve and fell back. Two of them made some show of effort to remain threatening, but to little avail. One frantic goon threw a plastic recycling receptacle at the clerk, but he just shrugged it off like a badass and continued to rush the retreating thugs.
