Kindly pee on the frog, sir!

In Africa there's a frog that changes it's skincolor from dark to light if you pee on it. Provided that you've been taking illegal substances, that is. Scientists now want to use this to nail athletes who use drugs to enhance their performance.

I realize, of course, that this is probably done in a lab with pipettes and such, but it's much more fun picturing it in other ways. In my head, there's a nervous looking athlete and a strict, skinny guy with glasses, holding a clipboard. They're standing by a table full of plastic cups. The metal kind with wheels that squeak, that they have in labs and institutions (not that I've ever been in an institution) and such.

"Kindly pee in this cup, sir! Yes, it's ment to be there. Try to ignore it, but be careful not to startle it so that it jumps out..."
