Maybe you should give this funny Birthday card from NobleWorks to a coworker that may need a hint about what the term 'Casual Friday's' actually mean. Or, you might just want to provide a good laugh for someone on their special day. No matter what the reason, this hilarious greeting card designed by Glen McCoy will be perfect for you to give. If you think about it, how many men would actually go to work wearing his 'wife beater' t-shirt, with his beer gut protruding out above his yellow, polka-dotted shorts?
