You should always make it a point to include birthday invitation wording that adequately represents the celebrant. Is the celebrant a humorous person? Or a serious person? Someone who likes poetry? Someone who likes sports? Your invitation should be tailor-made according to the celebrant's preferences. It's not necessary to consult the celebrant on how the invitation should be designed, but your knowledge of the celebrant alone should be enough of a guide. If you are making invitations for your own birthday, make sure the wording will reflect your personality.

Fun, witty people may appreciate having invitations with witty quotes on them. Something wholesome and "clean" would go over well in most caes. There are also quite a few "clean" passages that would suit every occasion - however, you must still exercise discretion. Not every celebrant would appreciate the use of humor on their invitations - and those who do, may be rather selective about the kind of humor to be employed!

Jokes about age, for example, require a very special sensitivity; you may consider it safe to include age jokes on an invitation for relatives or very close friends, but a more formal gathering may not call for such light-heartedness. If you are making invitations for someone else, the rule is simple: Do not make any attempt at humor that the celebrant him/herself will not make in front of the people who will receive the invitations.

Serious people may prefer elegantly designed invitations with poetic quotes on them. A favorite poem or quote pertaining to the passage of the years may be a great touch. Don't flood the card with thought-provoking quotes, though! One or two short quotes is generally enough.

And if you're making your own invitations, a quote that you made up yourself would give the reception more value. Remember that the birthday invitation wording would be most precious if it were chosen or made by the celebrant him/herself! After all, every invitation is not just a card, it is also a souvenir for the people who attend the birthday gathering - a little something from the celebrant to the guests.
