For the record, I wasn't there for the incident in question. It happened in Manchester and I found out about it in a roundabout way . I actually found the photos in question on the internet. The girl on top of the police car naked looked a little bit familiar, so I inquired around the ol' shop when I got back to YYZ, and sure enough, she worked for Angus too.
It's easy enough to imagine, somewhere between the pub and the crew hotel, one person dares another and pretty soon it's all over the web.
