Colin Baker played the sixth incarnation of Doctor Who.
Unfortunately, some very disreputable, unpleasant Who 'fans' have alleged that Mr Baker endorses their brand of misogynistic comedy, that is only VERY loosely connected to the programme.
Since then, THE Colin Baker has become something of an overnight meme, used to mock these same Who 'fans'
"Who told you could park there?"
"THE Colin Baker, bitch."
"I didn't do my homework. I have a note from THE Colin Baker"
