Old MacDonald had a farm ... and 'had his way' with at least one sheep, according to the Two Timing Jerk Funny Birthday Card from NobleWorks. The front of this hilarious birthday card shows a bright blue sky, green grass, cartoon picture of a man and woman walking hand in hand past the sheep meadow, while in the background, an angry ewe holds up a sign proclaiming the man a 'Two-Timing JERK!' The inside of the card is equally colorful and humorous, only now the she-sheep has calmed down and is holding up a sign with a birthday cake on it, and the good-natured greetings are 'Happy birthday to ewe.' Don't be sheepish and keep this fun and fanciful card down on the farm; dole it out to all those celebrating a wild and woolly birthday.
