There, templates found under "Mormon missionaries" here.
Some are mocking them, I do not endorse those temps, as the Mormons I've met (IRL) were pretty decent folks. I may have my reservations about the religion, but otherwise they're cool people.
Ironically, the ones I've encountered that do not leave such a favorable impression (as seen on this site) always turned out to be just pretending to be Mormons, using it as a cover. As most people are not that familiar with the specifics of the religion, it's easier for them to get away with without getting busted on it.
