Penguin and polar bear animosity reaches new cold relations heights, as delightfully and deliriously documented on the hilarious Happy Birthday card available here. While the hard working flightless tuxedo birds have to trudge off through the snow and ice to work every day, the protected white furred bruins do nothing but sit around eating junk food and drinking beer while watching TV. Any of your employed, unemployed, too young to work or retired friends and family members who are turning another year older and enjoy a good wildlife welfare joke will be heated up with hilarity and good humor when you gift them the colorful, comic and witty winter land animal Birthday greeting.
