The art of crapping in the toilet tank above and behind the toilet bowl. So you're taking the lid off of the back of a toilet, and crap in the toilets area that holds the mechanical parts of the toilet bowl.
Bob was so hung over, he told me that when the bar tender cut him off, he went to the bath room and delivered a top sider to the morning clean crew that was rank.

After he fired me, I went to the bathroom to get changed and left a top sider for him to clean up.
