When a self-confessed troll rings James O'Brien to gloat, the LBC presenter turns the tables on him and leaves the caller with egg on his face.
Vic in Islington phoned up to explain to James why he gets a kick out of irritating and abusing people online.
"I just like to poke fun at people and get a reaction," he admitted. "I like to argue with people, I like to disprove people's point...even if I agree with them.
"I like to get reactions out of them and wind people up basically....I just like arguing with people, winding them up, seeing how seriously they take it."
Vic had set out why he likes to troll people online and that's when James got to work "pulling [his] pants down and slapping [him] from here to next Tuesday" - without Vic even noticing.
Take a look above to see James give Vic the runaround - and the LBC presenter's fantastic sign-off line.
