Decode This If You Dare

Last night, when I exited the Long Island Expressway, I pulled up at the traffic light behind a small SUV that had the license plate HPY PNTS. What's the story behind that?

• Successful dieter who can now fit entire body in one old pants leg?
• Clothing designer who finally made a killing?
• Beer enthusiast?
• A guy who carries autoerotic devices in his underwear?

It was dusk, so I didn't get a look at the driver. Nothing to go on except my own wayward thoughts. Which could be dangerous.
