My favorite video of bullies getting the tables turned on them. The girlfriend of the bully is so annoying and seems quite eager to see her man beat up someone, but reacts with horror when the fly takes out the spider.
Moral: When a calm guy tells you he has no beef with you, you should listen and just walk away.
(Probably NSFW due to a bit of language).
