Telemarketers can be quite a nuisance, so why not give them a little hell when they call you? Sure, you can put your phone number on the Do Not Call list and be somewhat immune to them, but what would be the fun of that?

This clip features the most hysterical telemarketer prank I’ve ever heard. This guy has it all planned out, tape recorder in hand, and when the telemarketer calls he’s ready to just completely blow his mind. And he does so superbly.

I’m not going to give the whole thing away, but let’s just say that the man puts the fear of God into the unsuspecting caller’s poor telemarketing soul, and has him on the lookout for the cops. If you’ve ever considered a career as a telemarketer, this call just might make you think twice.
