Seein's as how I didn't notice this thread until now, I think that it's street legal to say :

HAPPY DAY AFTER YOUR BIRTHDAY, TWEEDSTER!!! Now Khandu said that "today" is your birthday, but I'm not sure which "today" he's talking about. If it's today, "today", why then, I wish you a Happy Tomorrow (which is the day after today, I think.)

And always remember Tweed, don't put things off until tomorrow.
Celebrate today. After all, Today is yesterday's tomorrow.

And if that doesn't toally confuse you, to quote my illustrious friend Bobert "Have a Danged Good Day, Whenever You Dang Well Feel Like It!!!!

And to quote another old friend of mine, Pogo, If today isn't your birthday have a Happy Un-birthday!!!

I think that about covers it..
