6. Peter Davisons Edible Accoutrement
In 'Time Crash' fans were treated to a meeting between the tenth and fifth incarnations of their titular Time Lord. Within the short episode, the Tenth Doctor says of his younger self, Brave choice, celery. But fair play to you, not a lot of men can carry off a decorative vegetable. This, indeed, pretty much summed it up. The Fifth Doctor, often likened to an Edwardian cricketer, wore a stick of celery on his lapel. This could've ended up as being another case of quirky for quirkiness sake, but the garnish was explained away on screen in The Caves of Androzani as being a safety precaution. He was "allergic to certain gases in the praxis range of the spectrum after all, and "if the gas is present, the celery turns purple". A useful accessory, to say the least. So the celery acts as both a warning and a cure for the Doctor, should he have an allergic reaction. Genius. But wait. Why did he have to wear it on his lapel? And couldn't the Doctor have just made a scanner that went ding to notify him of these dangerous gases instead? Anything would've been better than wearing a salad, surely?
