I was working with a young uppity know-it-all supervisor in urine microscopy and thought about pulling a prank on her.
At the back of my apartment is a tiny pond. I filled a small water bottle with some of the dirty pond water and brought it to work. I just have to wait for the perfect moment.
As she walked away to answer her phone, I replaced the urine sample on her slide with pond water. She started running around confused and thought that she had discovered new parasites!
