Ok, I got the first one. Use the non-slip mat so that you don't end up having a very very unglam accident where the entire ambulance crew will be snickering all the way to the hospital. No sir. Don't want that to happen definitely!
It's the second one that has me all baffled.
This one means you need to carry a tuning fork into the shower with you and once the shower hits the right note (Concert B-flat?), GET DA HELL OUT OF THE SHOWER!!!
