A funny birthday message is a humorous quote, wish, greeting or saying someone delivers to a person on his birthday. One example of a funny, general birthday message is: "Happy birthday! Birthdays are nature's way of telling us to eat cake, so let's get to it!"
Many funny birthday messages bring up age and the notion of getting older. An example of a funny birthday message that lightly makes fun of age is: "They say that with age comes wisdom. I’m not so sure… I've met a lot of really stupid old people. So far, you're not one of them. Happy birthday."
Funny birthday messages are good for livening the mood and for giving the recipient an opportunity to laugh. Messages can include simple jokes, puns or witty remarks, and can refer to a variety of birthday-related subjects such as aging, family, parties and celebrations. Good funny birthday messages should be respectful and complimentary to the recipients, and should not aim to insult them or dwell on their hang-ups. People can also give messages that are self-deprecating and implicate themselves, or they can personalize them for friends and family by bringing up personal traits, shared histories and unique features of their relationships.
