That's a switch! The grinning young stud pictured on the front of this Birthday Joke Card had three or four dates a day; while the grumpy old geezer pictured on the inside of the card is down to prunes. That's a different wrinkle on the situation, all right. This colorful, humorous, cartoon card dishes up the sweet and sour 'Happy Birthday!' good cheer for anyone with a sense of humor (and some remaining teeth) to chew on.
