It's something TV nerds like me get paid to know.

But if you look at the guy playing Christian Slater's best friend on NBC's Bourne Identity-style adventure, My Own Worst Enemy tonight, you will see Mike O'Malley -- a beefy, everyguy standup comic who flamed out spectacularly in a self-titled sitcom for NBC in 1999.

Less geeky viewers may recognize him from CBS's mediocre comedy Yes, Dear. But who knew that a guy who once made his living playing real-life versions of Homer Simpson, would be so effective (and, dare this geek say, cool) as another secret spy-turned-office drone in his off hours by a chip implanted in his head.

As I noted Sunday, this is one of five great new shows debuting this week for our TiVo-ing pleasure. Check the early part of this clip to get a look at O'Malley's shedding his schlubby image:
