Hey it's happened to me for real. We rented a cabin in Denmark, (indoor plumbing) but not sewer cuz it was too isolated. Anyways, after a day of sightseeing, came home to use the WC , opened the lid and was about to sit down and a darn frog was in the bowl. After my panic attack and screaming, I flushed him back down about 20 times. My girls thought I was so mean! Hey that was my territory, not his!
