In news from China to make you wince, a young boy cycling to school was impaled on his seat tube following a fall.
The saddle bent forward as he came off, sending the seat tube into the boy's anus.
The bike had to be cut away from the boy's body by fire fighters before he was taken to hospital and the rest of the metal tube removed.
Fortunately the injury to his rectum, which can easily be fatal, was successfully treated, according to the website Opposing Views.
If you ever find yourself without a saddle for any reason, take some tips from this video of the Norwegian Kurt Asle Arvesen who rode 20km of the Paris Robaix without a seat - legs of steel.
After an unpromising start, having to be bribed by her parents to learn to ride without stabilisers, Sarah became rather keener on cycling in her university years, and was eventually persuaded to upgrade to proper road cycling by the prospect of a shiny red Italian bike, which she promptly destroyed by trapping a pair of knickers in the rear derailleur.
