If you don’t mind uploading a photo of yourself to their website or looking at an eerily grinning Joe Biden, you can get a pack of free Trident gum. However, be warned! The site has a map that’s dangerously addicting in that you can zoom in on your zip code (or anywhere, for that matter) and check out all the other local people who submitted a smiling photo. I went to my brother’s hometown and eventually found him before realizing that I’d just spent 45 minutes looking at photos of strangers. Hooray for time management!
