Get the To have my pants pulled down mug.
April 22 is national pull your pants all the way down while using the urinal day. Its pretty self explanatory but just in case what you do is anytime you need to take a piss on April 22 you have to drop your pants down all the way. a good rule to follow for this day is if your ass isn't out you need to get the fuck out(of the bathroom). it doesn't matter if your cheeks are pastier than ranch everybody is gonna be doing it.
