Originally, the 100% cotton Dr. Who Big Tardis Lounge Pants actually acted like the famous police call box from Doctor Who...but apparently people didn't want their legs going on time-based adventures without the rest of them...plus a bunch of disembodied torsos floating around is kind of morbid(though well within the range of a Doctor Who story). At least now you have something to wear during those marathon watching sessions with the Dr. Who Big Tardis Lounge Pants!
