Fun and free thyroid and spleen e-cards available for all your friends and family having not-so-fun thyroidectomy and splenectomy procedures. We've also got a vasectomy sympathy card with happy testicles and a pair of high-fiving kidneys to give to someone generous to donate his or her own kidney. Don't see the special guts-related e-card you need? Let us know and we'll try to make something special.
