Sleeping is overrated. Sure, it keeps you sane and healthy, but who needs sanity and health when celebrating a birthday. The perfect gift for your favorite night owl, these hilarious birthday cards are also very true. Remember last year on that Tuesday when you woke up rested and ready for work? Of course not. Remember when an epic night ending with a sunrise and a conversation? Well, maybe. In any event, birthdays are a time for a bit of irresponsible behavior.
