My mother-in-law worked as A&E sister for many years so she got to attend various incidents: The most common FBUA incident they would deal with was gentlemen who had inserted deodorant containers and upon removal of said deodorant container the lid would become detached and firmly stuck. There was the man who thought it might be pleasant to experience the delights of the suction power of one of those handheld dustbuster vacuum cleaners. Except he removed some pieces to get a better fit resulting in the need for surgery after encountering the spinning fan blade. Ps. I won't mention the woman who pleasured herself with a glass drink bottle and in doing so created a vacuum so she couldn't remove the bottle. This was remedied by drilling a hole into the bottle to balance the pressure.
