Rump Rocket
So ,, a 23 yo Australian woman goes in for an MRI scan , they tell her that she cannot have any metal anywhere near her during the MRI scan because of the powerful magnets , and the woman confirms that she has no metal with her.
Well she decided it would be ok to leave a sex toy inserted in the back door because the toy had advertised itself as "100% pure silicone" and apparently somebody misunderstood something because it sure as hell did have a steel core.
So when they activated the scanner , its ripped the booty plug out of her booty and shot the feces covered toy through her body and lodged it in the armpit of the now screaming woman.
It appears as though she is going to survive it , so she doesn't win a Darwin Award , but she gets an honorable mention.
