The Vanishing Moustache Prank

What evil prank have you pulled off? My mum's laptop wallpaper was a picture of her granddaughter. I copied the picture 100 times and made her wallpaper a slide show of the same picture over and over again, so the file would change but nothing would change visibly on the monitor. The pictures would change every 10 seconds. On one of the images I painted a tiny little curly moustache on her. So randomly for 10 seconds my niece would have a moustache. My mum thought she was either losing her mind or had a computer virus and everytime the moustache popped up, it was gone by the time she tried to show anyone.

A Reddit-style screenshot shows a comment describing an elaborate prank involving a grandmother's laptop wallpaper. The prankster made a slideshow of the same family photo, secretly adding a tiny curly moustache to one frame, making the moustache appear for only ten seconds at random intervals. The joke is the victim's confusion and inability to prove that anything strange happened, so this meme is sent as a reaction to clever, harmless mischief.
