Yes that's Hal from Malcolm In The Middle (Bryan Cranston). I think this is the best drama on American TV at the moment. I'm going to be lazy and paste the opening synopsis from wikipedia:
"Walter White, a chemistry teacher with a pregnant wife, Skyler, and a son with cerebral palsy, is diagnosed with stage-three terminal lung cancer. Determined to develop a sufficient inheritance for his family before his death, Walter enters the drug trade using his chemistry knowledge to cook remarkably potent methamphetamine (crystal meth) with Jesse Pinkman, a former student."
Believe me, if you haven't seen this show then do whatever you have to do to watch it. Bryan Cranston's performance is fantastic (he won two Emmys for best actor). There are two series and the third will be screened in March 2010 in the US.
Seriously folks, watch this show. You won't regret it. I promise.
