My favorite gag when fishing is when no one is looking I take a live fish and put it down someones pants. Its a lot of fun for everyone involved, except of course for the person with the fish in the pants and the fish.
After reading this I may rethink doing it again. Or at least be a lot more careful next time I clean my fish tank.
Fish found in boy's penisDaily Telegraph--A 2cm long fish apparently found it's way into the penis of a 14-year-old boy from India in a bizarre medical case. The patient was admitted to hospital with complaints of pain, dribbling urine and acute urinary retention spanning a 24-hour period. According to the boy, the fish slipped into his penis while he was cleaning his aquarium at home. Professor Vezhaventhan and Professor Jeyaraman, who treated the boy and later wrote a paper on the case, explained: "While he was cleaning the fish tank in his house, he was holding a fish in his hand and went to the toilet for passing urine. When he was passing urine, the fish slipped from his hand and entered his urethra and then he developed all these symptoms." After detecting the fish in the boy's bladder, Vezhaventhan and Jeyaraman used a technique known as cystourethroscopy to insert a special set of forceps down the patient's penis. Unfortunately, the fish was just too slippery to grip, so they resorted to using a rigid ureteroscope with a tool attached that is normally used for removing bladder stones. The fish the urologists removed, which Practical Fishkeeping believes to be a small member of the Betta genus, measured 2cm long and 1.5cm wide. He was later admitted into counseling to help him overcome any trauma.
It doesn't give the common name for the fish that went into his penis, but the most popular and abundant type of Betta is the Siamese fighting fish. So it probably went in fighting too, poor boy. I feel for ya!
