On the Dr. Who DVD 'Earthshock', go to the special features menu. Highlight the '40th Anniversary celebration' feature and press LEFT. A 'Doctor Who' logo will appear. Press enter/select. You will see a short clip from 'The real McCoy' featuring a clip from Earthshock with a few humourous adjustments. Note the embarrassingly exaggerated canned laughter. Listen out for how suddenly the laughter cuts out when the guy speaks- very fake. Apart from that, good sketch.
