“She Can’t Lie”: Malcolm Wentzel Pranks Domestic Worker Thembi With a Drink Taste Test

• Malcolm Wentzel finally got his revenge on Sis Thembi by pulling off a drink prank during what she thought was a genuine beverage advertisement
• Thembi had no idea that her glass contained a completely different drink from what Kiki and Roxy were having
• South Africans could not stop laughing in the comments, with many saying Thembi is the most honest person on the internet

It was payback time. Malcolm Wentzel, one half of South Africa's favourite TikTok duo with domestic worker Sis Thembi, posted a video on 10 April 2026 that had SA in tears. He set up what looked like a proper advertisement shoot for a peach Bellini drink called Simonsvlei Bellini. The setup was complete with a branded board behind Thembi as she sat at the kitchen table. She had no idea what was coming.

While Thembi sat looking straight ahead as instructed, Malcolm, his wife Kiki, and their friend Roxy poured the real Bellini for themselves and slipped something completely different into Thembi's glass. It was a lighter coloured drink that tasted nothing like peaches. When it was time for the big taste test moment in front of the camera, Kiki said it was peachy, Roxy called it fruity and bubbly, and then it was Thembi's turn. Her face said it all before she even opened her mouth. She described it first as an awful drink. After persuasion from Malcolm, she lied and called it a very 'lekker' drink. Her face and the tone of her voice told the real story. The girls eventually cracked up and gave her the real drink, which she immediately loved.
