So given the number of people who pee their pants over kittens in buckets, it's no wonder that the Denver Zoo decided to try its hand at the whole animal-photos-with-words thing via a series of free, downloadable Valentine's Day cards. They feature clip-art hearts superimposed over adroable images of monkeys, bears, giraffes and the supersized feline seen here -- and while their effort is no LOLCATS, it could be a cheap alternative for parents looking for an excuse to not buy their kid another pack of Hannah Montana valentines. Awwww!
