If youre an ordinary person, you would think that a sailor mouth was harsh. But if youre a Whovian, and a Classic one at that, you would know the Fourth Doctors mouth is even harsher. While the Fourth Doctor is a remarkable man, who loves to eat and share jelly babies (on that note, would you like a jelly baby?), he also has the tendency to insult humans when hes angry, a trait that has been passed on to all his future regenerations as well. His words lack profanity but be their target and youll be in tears in no time at all. Unless youre his companion, that is. Over the years, his companions have been told off numerous times (poor Harry Sullivan), often making for laughable instances during critical situations. Hes had condemnations for basically everything starting from K-9 cheating in chess and the usual witty banter with Sarah Jane, all the way to Romanas inability to make tea. However, by some miracle, or resilience, rather, no matter how many times theyve been told off, they have never left his side. So, in honour of Tom Baker's 81st birthday this month, here is a list highlighting some of the Fourth Doctors definitive insults, and all being well, you will - unlike Mona Lisa - sit still with your splendid eyebrows and reminisce. And maybe have a laugh or two by putting some of these insults into good use, too. The choice is yours.
