10 Doctor Who Bloopers You Need To See
6. K9 On The Lash
Though not technically a blooper in the same vein as the others on this list, this clip is too glorious not to share.
Included as an extra on the DVD release of The Armageddon Factor, this moment - reportedly a part of the BBC's 1978 Christmas tape White Powder Christmas - features the Fourth Doctor and Romana sat on the floor of the TARDIS getting rather close and drinking gin... before offering some to K9.
Witnessing the robot dog chugging booze through his "straw" and singing a squiffy rendition of We Wish You A Merry Christmas has never been on any Whovian's bingo card, but nonetheless, it's a sight to behold.
Tom Baker then goes on to ask K9 what he wants for Christmas, to which John Leeson responds:
"Enough ball bearings to last the series through, and fewer sill irons on the floors of the planets we visit."
This was clearly a comment on the many mishaps that the K9 prop suffered during filming, and it amused Baker greatly, who started to chuckle.
Whatever is actually going on here, it seems as though everyone was having tons of fun - including the crew, who can be heard laughing just out of shot.
