A man accidentally advertised far more than he bargained for while trying to sell a microwave on social media.

He posted a photo of the kitchen appliance to a private Facebook group in Taiwan and wrote: "Brand-new microwave, appliance cabinet size, never used. Pickup or meetup both possible."

He was selling appliances for 2,800 TWD (70 GBP).

But online users were left shocked after they spotted something very unusual in the photo. In the reflection in the microwave's glass door, they spotted the man was completely naked with his private parts on display.

The embarrassing snap quickly went viral on social media platforms.
