Doctor Who TARDIS Bath/Beach Towel
It's amazing to us that Dr. Who's mode of transportation has never changed in all these years. Do they still have police boxes in England? You'd think that he might try to change to adapt to the technology of the day, but then again there is no "present day" for a Timelord.
In any case, this towel is bigger on the inside. It may or may not open up into a huge room below the beach, but hey, it looks awesome.
There's also an alternative towel design, the exploding Van Gogh style.
