You're almost guaranteed to have a good time shopping for a friend at Tangerine, a colorful, whimsical shop brimming with quirky gifts. Better yet, bring a friend along. Then you can share the fun as you snicker at the silly merchandise: dental floss that tastes like cake frosting, sunglasses that would do Elton John proud, "Happy Gum for Your Crappy Life," and pens that say things like "Nudist Camp" and "Center for Sex Addiction" so no one will swipe them from you. Prices may not be a bargain, but where else are you going to find things like squirrel underpants? (Don't ask.) It's probably not coincidence that Tangerine Is just a few blocks from Mayo Clinic. If laughter is indeed the best medicine, there couldn't be a better spot to stop for a get-well gift.
