WATCH: Whackhead AKA Oom Arthur shocks husband into eff bombs after wife swop prank

Another week, another prank!

This time, Darren "Whackhead" Simpson takes on the role of cheeky Oom Arthur, a bold 65-year-old with a very unusual proposal for his neighbour: a wife swap... or swinging as Arthur calls it.

The call starts off with Uncle Arthur casually suggesting, "just one swop... Dorette will show you a good time. What time should we arrive?"

The stunned neighbour doesn’t hesitate, "F* off,"** he snaps.

But Whackhead pushes on, clearly enjoying the chaos.

That’s when things take a dark turn.

The neighbour fires back: "I will show you also a very good time... in your grave. Don’t talk about my wife like that!"

From there, the threats roll in, this time, in Afrikaans, and when that happens, you know it’s no longer just a joke when an invitation is really a threat, "you know what, come, me and my wife will be ready in our underwear..."said the prankee.

After the call with Whackhead, this uncle immediately called his wife to tell her about the offer that got him "in die bliksem in".
