On TV or not on TV

Frightful business in Scandal! with Abigail being blown to bits in a car explosion. Overcome with grief(?) I disappear. I am back on the Ersondes set working like a dog and loving it. I wonder where the expression working like a dog comes from? And then we have it’s a dog’s life – a total contradiction. Incidentally SABC will be releasing Erfsondes on DVD soon…
