Oh Hallelujah, praise the lord 'cause it's mother freaking Friday everybody! After the work day is over you can ignore all of your responsibilities, because that's Monday-your problem! Who cares! shred your important documents! spray-paint your boss's office lime green! Throw all of the ceramic mugs in the break room on the ground and yell 'mazel tov'!
(Only do this if you want to get fired.)
