Shakespeare once famously asked "What's in a name?" When it comes to pet names, the answer is puns, pop culture references, and a little bit of poop. For the third year running, Veterinary Pet Insurance Co. (VPI), the nation's oldest and largest provider of pet health insurance, is saluting those four-legged friends with names of a truly unforgettable nature. VPI employees selected 50 unusual dog and cat names from the company's database of more than 485,000 insured pets and narrowed them down by voting for the 10 most unusual names for each species. Following are the 10 Most Unusual Dog and Cat Names for 2010:

"One of our favorite parts of putting these lists together is talking to the pets' owners and finding out how they came up with such imaginative names," said Curtis Steinhoff, director of corporate communications for VPI. "Strangely enough, a lot of them tell us they ruled out names they'd be too embarrassed to shout in public when calling their pets back to them. When you think about the names these owners finally decided on – like 'Lord Chubby Pruneface' and 'Optimus Pants,' – it really makes you wonder what didn't make their cut."
