Pop open the champagne: It's Middle Name Pride Day! In celebration, everyone's supposed to reveal their middle names to three people who don't know it. What if you learned, probably the hard way, that your middle name might make other people laugh, gasp, or punch you in the nose? Then take comfort in knowing that you're in good company. Many of the most famous names around have middle names they'd probably just as soon keep out of the limelight.
