The hot-headed woman featured in the clip decides to direct every ounce of concentrated anger she has ever felt - from birth to adulthood - towards an innocent call centre agent.
And it's not like there's a steady build-up to her anger. She's pretty triggered from the get-go. Just listen to the contempt in her voice when she enunciates the call agents name at the beginning.
Catch Whackhead’s Prank Call on Kfm Mornings with Darren, Sherlin and Sibs at 08:10, every weekday morning, only on Kfm 94.5.
Telemarketers are known for their relentlessness. No matter the circumstance, they'll push through to make a sale.
And naturally, whenever Darren "Whackhead" Simpson receives a call from one, he makes it his mission to push their limits in the hopes that they'll hang up first.
Remember when he faked a break-in and near-death experience?
In this prank, Whackhead feigns interest in purchasing the telemarketer's insurance product. He goes on to break his precious piggy bank and slowly count all his copper coins.
Darren "Whackhead" Simpson is an avid vinyl record collector and was recently gifted an assortment of records from a 73-year-old fan from Parow.
While going through the collection, Whackhead came across a 'Best of John Berks: 1983' record. John Berks was a former radio personality and the original prankster in South Africa.
Listen to this John Berk classic prank where he calls from a licencing department about a dog complaint. Does the prank still hold up today? We think so!
