Nope. Dead serious. We were quite surprised by this. Even the wedding consultant (we used one since we didn't know the rules in P.R.) was surprised at that bit on the U.S. forms.

The nurse though, was a little quicker on the uptake than we were. She was surprised, but quickly came back with, "well, if we find you have syphilis or gonorrhea, they'll think you're an idiot."
