This secret reminds me of an old episode of The News Quiz where someone, I think it's Miles Jupp, says "I can't hear showtunes. I once had a car trip to Southampton with John Barrowman and ever since then I can't hear them. All I get is just a low hum and jazz-hands waving." Which I think says as much about Barrowman as you need to know. I still think he's awesome.
