So Paula and I were watching CBBC's programme about behind the scenes on Dr Who. There was a spot where they were supplying sound effects for some fiction written by a viewer and we wondered idly if it would be slash. And then we wondered about, given the time travelling theme, doctor on doctor slash.
So we found this livejournal, called timeslipping subtitled "doctor/doctor is self/love". And then we found out what the sonic screwdriver is really for.
