Co-worker No.1: "Could you just come here a minute? Walk through there and tell me if you smell gas, would you? Maybe it's just me, but I just think I smell gas. Did you smell gas?"
Co-worker No.2: "Nope. Smells fine to me."
Co-worker No.1: "Oh good."
JJ's e-mail to Co-worker No. 2: "The answer to that question is always 'Yes! It stinks!' You just cost us a half day's holiday. It's as well there ISN'T a gas leak... with a bright spark like you around we'd all be dead by now."
