What's the difference?

Two sample sentences that Tetsuo and I were discussing just now (yes, this is how we spend our Saturday nights...)
What's the difference between them?
I came home to find my house stolen by aliens.
I came home and found my house stolen by aliens.

I say that using "to find" instead of "and found" adds an element of surprise, but this may not necessarily be true...

Opinions please!

ninety days

They said the first ninety days would be the hardest, but I made it through O.K.
They said I should be hospitalized,
but I went to work anyway.
Those ninety days are over now,
and I'm no worse for the wear.
I think I feel myself coming back,
though this time with less hair.
