Your Sperm: Funny Birthday Card for Men

When those little semen tadpole creatures have grown into full fledged frogs in a guy's testicles, then yes, any qualified doctor can tell that their male patient hasn't engaged in coitus for quite some time. That's the hilarious, clever joke featured in comic X ray form on the cover of the colorful, humorous Happy Birthday card available here. Any of your friends, relatives or workmates who have reached another (perhaps celibate) year older will be squirming with laughter, good cheer and delight when you squeeze or shoot them out the hysterical, garrulous Birthday gag greeting.
