Backwards Birthdays

Because the Arizona MVD employs only the least literate and intelligent portions of society, by government mandate, mistakes on driver's licenses are disconcertingly common. Usually, however, they are uninteresting and/or annoying. Like the time my permit said that I was 5'2" and weighed 95 lbs. In Charlie's case, the mistake is more, shall we say, useful. His birthday, the second of May, was printed backwards, as February 5th. Hence, I am throwing him a surprise backwards birthday celebration. We will, of course, have our cake first, sit under the table, and let the guests blow out the candles. However, I'm sure you could come up with more exciting details...any genius thoughts?
