The Soup Dragon.
Seriously, that would be way cool.
Or the dragon from Ivor the Engine.
<I am not obsessed with dragons BTW, and until tonight had never thought of dragons since I lived in Australia and went to watch Rugby League...but dragons seem like a good enough job to me>
If it has to be a 'real' job...I'm fairly happy with what I do, I have done a few jobs in my time and enjoyed them all. So, back to the Soup Dragon option I suppose....
