The pranks are fukking bollocks now anyway, most well known pranksters use actors, and the 'pranks' seem to revolve around painting black people in a bad light and paying girls to give reactions to their trolling pick up lines. Really lame.
The only you tube prankster I ever liked was jack vale, when he first started out with the fart pranks, but then like some of them do, he got more well known and started using actors as well. But the fart pranks were real and funny.
The best pranks these days on your tube are the soundboard pranks, check out, satanic racist, chris the hacker, jackass plumber, frank garrett, the victims are real, although I prefer it when they phone up business's rather than private homes.
check out 'billy bob james', 'stilwell department of public safety', afghan prankster, harrassment caller, and my personal fave loon3y tube you tube channels.
