Barry I empathise with you (Mr Smelly Hands and arms)
Our shower drain was blocked a few months back and the gunk in the drain was just laughing at the plunger... so off to Bunnings we went and purchased a manual eel. Well, as well as the obligatory disgusting stinking grimy decomposing hair ball in the drain mixed with soap scum and other icky stuff we pulled out a chopstick (!!)

, a heap of hair bands that my daughter has discarded in the shower, a few hair clips, a plastic dinosaur, half a plastic soldier and a popped balloon. New rule in the house for the kids: NO TOYS IN THE SHOWER.
Ick.
