Guess what? I got a fever! And the only prescription... is this more cowbell. Design inspired by the classic Christopher Walken and Will Ferrell sketch. Printed on our super soft ring-spun & combed cotton unisex T-Shirt. Or upgrade to our Luxury vintage heather edition (cotton/poly blend) for an even softer, more durable, classic look. We print & ship all of our high quality graphic tees in the USA.
