On a school residential activity a colleague of mine dropped a table tennis ball into each of the boys loos. She explained that it would give them something to aim at and would not flush away. It bobbed up clean a perky for the next user!
I also hate all "girlie" activities - they give me the creeps. Most (although not all) of my friends are men. That includes my best friend who I've been married to for thirty years. (I really must spend the next thirty sorting out his aim!)
