Doctor Who: Top 10 Insults Used By The Fourth Doctor
5. Shut Up, K-9!
One of the lighter and admiring things on Classic Who has to be the friendship - or loyalty, rather - as demonstrated by K-9. It was absolutely bonkers when Rose and Mickey referred to him as a tin dog and used the term disco to describe him, because theres really no one who is a better companion than K-9. Except for Sarah Jane, of course. Hes extremely clever and that can be a bit annoying when whatever you ask him is a turn of a phrase, like immersed instead of bathing and the helplessness you face when you cant enunciate walk without him getting ready to accompany you. But when it comes down to providing lasting support to the Doctor, he is not Mark III, but Mark I. Think of it as an endearing insult towards a younger sibling or simply someone who likes to tag along and you dont in the least mind it.
