You can "check in" to restaurants and bars, so how about health clinics while you get tested for sexually transmitted diseases?

Foursquare, the online application people use to tell their friends and strangers where they are, is offering a special virtual "badge" through September to people who do just that.

The badge is part of MTV's "GYT: Get Yourself Tested" campaign. MTV says the idea is to remove the stigma attached to getting checked out for STDs.

Foursquare users already receive scout-inspired merit badges for a range of check-in accomplishments. These include "Gym Rat" for hitting the gym 10 times in a month or "Crunked" for checking in to four or more places in a single night.
