Kirby served his mission for the LDS church in the good ol' state of Mississippi, so he didn't have any issues with parasites, like those serving on foreign soil often encounter.
I haven't been to South America lately, but I've been suffering some typical symptoms of parasitism.
I went to the doctor to get a diagnosis, and it turns out I have managed to contract a parasite.
The bad news is that it's going to take another couple of months to purge the parasite from my system.
The good news is that he's a pretty cute parasite.
P.S. Don't EVER--under any circumstance--google for images of parasites when pregnant. Or maybe ever.
