Pure Evil: Hidden Moustache Laptop Prank
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.

Overview
This image is a screenshot of a Reddit discussion thread that asks users to share the evil pranks they have pulled off. The top-voted comment describes a petty, lighthearted prank a user played on their mother: the mother's laptop wallpaper was a photo of her granddaughter. The user copied the photo 100 times to make a 10-second rotating slideshow wallpaper, with only one copy edited to add a tiny curly moustache to the granddaughter in the photo. The mother repeatedly spots the moustache briefly, but it always disappears before she can show it to other people, leading her to believe she is losing her mind or her laptop is infected with a virus.
