What are the odds?

It's my wife Marian's birthday, and at one point today she asked me to look up things that happened on this day in history. Among the factoids I uncovered is that she shares a birthday with Florence Henderson...

... which freaked us the hell out, because I happened to share a birthday with Robert Reed.

What does this mean? Do I have to get a perm? Replace our lawn with astroturf? Hire a wisecracking maid? Host a variety show?
