An unnamed 13-year-old Chinese boy who claims he was 'curious' about his genitalia inserted a USB cable so far up his penis, that it got stuck. The boy inserted the cable about 20 centimeters up his urethra and and it knotted in his bladder. 

When the boy arrived at the hospital, doctors tried to use lubrication to pull the cable out, but were unsuccessful and the boy was left in intense pain. He was transferred to the Harbin Children’s Hospital the next day. 

Talk about your fun-time gone wrong! This kid is going to have penis issues for a while.

"He cut off one end of the cable and inserted it into his urethra [...] The cable reached his bladder, where it tangled and ended up in a knot, so when he tried to pull it back out, it became stuck." Doctor Xu Liyan, the hospital's resident urologist, said.

The doctor had no choice but to operate on the boy. 

Doctors cut into his bladder to find the knotted cable, cut off the tangled section and removed the remaining cord through his urethra. The boy was discharged 2 weeks later. 

It's safe to say his curiosity has been satisfied.
