If your ass is itchy while playing volleyball on the beach, you may not want to scratch it, not until you check and see if anyone's looking at least. Or, if you don't mind what people think, go for it, scratch that itchy ass. If you've ever caught a friend scratching or picking at their ass, this would be the perfect birthday card to send their way. Or maybe you just have a friend with a birthday coming up who needs a good laugh. Either way, this is a funny birthday card anyone with a since of humor is going to enjoy.
