No. A mug is not just a mug. As a bit of a tea drinker, let me walk you through some of my favourite mugs...
This is my favourite mug of all time. It's kind of square on the outside and round on the inside - which is most fitting. It's my morning mug and my writing mug and is in constant heavy rotation. Complete with Scarecrow, Judoon Captain and obligatory Dalek, it's damn classy.
Next, we have the Dalek bowl. In times of great stress, this holds the maximum amount of tea I can possibly make. It's not my favourite but it is highly functional... everybody must have a functional mug. It's only right.
This is my second favourite - the other side has a Cyberman on it (that's the drinking side). Often in use when the square one is hidden underneath much washing up. This one came free with an easter egg... nice.
...and so we move on to the visitors mugs. The kids loved last easter because I went a bit overboard on the eggs that had mugs with them. Both the 24, WWE and the LOST mug came this way - there was also a Desperate Housewives mug and I'm a bit disappointed that I never picked it up as well. So there you have it.
I would however like to point out that I'm really sad... I was actually testing out this Sony Ericsson CyberShot to see what it was capable of.
Experiment over.
