The Doctor's Trunk

When I was a kid, we used to play a game called "I packed my trunk..."

The idea was, you chose a letter of the alphabet and then had to go round the circle listing, and correctly remembering, items beginning with it.

Let us imagine that the Doctor has a trunk filled with items beginning with, say, the letter C. Suggestions gratefully received. Here are mine:

Camera (first one ever invented)
Cards (to win back the TARDIS in a game of poker, useful in emergencies)
Comb (oh, that's where I put it!)
Chocolate biscuits
Chocolate
Carpet that he always meant to lay in the control room
Calender (New Byzantine)
Conkers (fun to have in pockets)
Cassandra's moisturiser
Chalks (to leave mysterious pictures of Bad Wolf on strategically placed walls)
Castanets (for visits to Barcelona. The place. Not the planet)
Cod Liver Oil (to keep him regular)
Capers (for detox)
Cat treats - useful when trying to recover animals lost in space-time continuum
Catalogues (he drove Jackie mad by filling in forms for them whenever he was hanging around the Estate)
Cabbage (that's where he hid it when he was a little boy on Gallifrey. You can't imagine him eating it, can you?)
Converse that fitted previous incarnations
Cannibalised Controls and Console Parts that may come in useful someday

Any other suggestions? (Note, for the purpose of this survey let us assume that the Doctor is asexual, or at least keeps anything that suggests otherwise safely in his pockets).
