Robert Downey Jr proves why smoking is bad

If any ladies want a shot with Robert Downey Jr., I have the perfect pick-up line for you. "Are your pants on fire, or are you just happy to see me?"

Allow me to explain. Robert was on the set of the Sherlock Holmes movie he's filming with Jude Law, when ashes from his pipe fell onto his lap and set his pants on fire. Luckily, Jude was right next to him and helped him put it out.

Since no one was hurt and both Robert and Jude are absolutely fine, I can say -- HAHAHAHAHAHAHAHAHAAHAHA!!!!!!!!!!
