Haha. Pledge on the wood floor, classic. We did that on accident and spent the next week slipping on it until we scrubbed it with wood floor cleaner. It took scrubbing it three or four times before it was no longer a hazard.
This is how I got caught for throwing a house party in high school. Cleaned the kitchen floor with pledge, left a slippy spot and my dad slipped and fell on it the moment they got home.
