Clinic & the mug

Fired off a few rounds at Clinic's 'Semiotics' night a couple of weeks back, the one directly below is of the Lewisham Fun Police informing Large Boats their set would have to be a few songs long due to excessive noise. That's why they're called the fun police. The other shot is an Independent mug I found in the middle of Vesta Road at 3am after a house party. Whose mug was it and how did it get there?
