A Cleveland Dry Dock is accomplished by entering someone else's bathroom, bending down and turning the water supply to the toilet off, flushing to drain the remaining water in the tank, then proceding to leave a huge Steamer in the bowl. Always use the Carpenters Cut
or drop a Hydraulic Shit
so the need for toilet paper is eliminated thus displaying your work of art without toilet paper covering it so the owner of the shitter will have to come face to face with your masterpiece to turn the water supply back on.
Dude, I stopped at my Ex Wife's house to drop the kids off and left her a Cleveland Dry Dock in her half bath.
