A heavy hint, possibly

A picture of drug control expert David Cowan raising a glass adorns the front page of the in-house magazine of King's College London to mark the academic's role in the testing of athletes heading to the Olympics.

The glass in question is a glass bottle that's half full (or should that be half empty?) of urine. It is labelled, a little unkindly, "UK Sport". Hopefully, this is not intended as a comment on Britain's medal prospects at Athens.
