Well, it actually happened. And the results were not anywhere near as romantic or sweet as the song. The tragic details are here.
"If you like Pina Coladas
And getting caught in the rain
If you're not into yoga
If you have half a brain
If you'd like making love at midnight
In the dunes on the Cape
Then I'm the love that you've looked for
Write to me and escape."
Best of the Web pointed me to this tragic little soap opera gone bad.
