Favourite mug

As I don't like any hot drinks (except hot cordial), I don't own many mugs. However, I absolutely love this one, and use it whenever possible. It is a mug I won when I took part in a plant science pub quiz at a summer school during the summer holidays after my first year at university. It was such a great week, and I am so happy that it introduced me to plant biology. It's also the only pub quiz I've ever won!
