"Welsh On A Plane"
This programme is really stretching credibility. I simply refuse to believe that more than two black people work for the CIA.
Also, Sheldrake's morphic fields theory is science so bad that it's actually worse than saying "it's probably God or something" (c.f. "The Shakespeare Code", in which Davies-by-proxy is so paranoid about the idea of the Doctor believing in magic that he adds pseudo-science which makes less sense than interdimensional aliens having magic).
Nice chemistry, though. I mean the actual chemistry. I was tearfully reminded of Patrick Troughton making stinkbombs and killing giant crabs, although Troughton probably wouldn't have done the bitch-slapping.
