I have a myriad of these but the best one happened to Dearest on our first trip north into the wilds of the Daintree.  He ventured forth one night without his torch to visit the dunny & while in no position to scream & run had something cold & clammy suddenly latch to his buttock!  Who knew green tree frogs lived *in* the dunny?!

 Ugh! Green tree frogs anywhere on my person would result in screams for sure!

My toilet nightmares were in China. The floors were always awash with detritus and I also tried to uphold my mother's maxim about never sitting on the seat. So between kangarooing it, holding my jeans cuffs out of the slush, and using my head to hold the non-closing door shut, I contorted and wished for a camel's bladder.

Hmm, we seem to have an animal theme going here: frogs, camels and kangaroos!
