Get a lesson in quantum mechanics from the Doctor with this black sweatshirt from Doctor Who. The Tenth Doctor's perplexing exlpanation from the classic episode "Blink" is printed in a TARDIS graphic across the front: "People assume that time is a strict progression of cause to effect, but actually from a non-linear, non-subjective viewpoint - it's more like a big ball of wibbly wobbly timey wimey stuff." Made from heavy 50/50 cotton/polyester blend. Timey-wimey Detector not included.
