For reasons yet unknown, a Chinese boy stuck a USB cable up his penis, which wound itself into a knot (the cord, not the penis), and required surgery to remove.

The 13-year-old from China’s Heilongjiang province was taken to a hospital last month, according to Singapore’s Strait Times, presumably because he couldn’t pull the cable out. How? Why? I have questions!

Apparently, the teenager cut off one side of the USB connecter before inserting it into his urethra, thank god. It measured 10 centimeters-long, and had reached his bladder, causing blood to appear in his urine, doctors said.

The Times reports that he did it all “out of curiosity.”
