2x7 - My Wife and Kids

Lou Rawls guest stars in an episode that takes a lighthearted but informative look at a serious problem: colon cancer. It's especially acute among African-Americans over 40—and guess who's 40? Not only that, but Michael has been having bathroom problems. Still, he won't go to the doctor. ""What is it with men?"" Janet fumes. ""You take better care of your cars than you do of your bodies."" That doesn't change his mind, but the thought of not being there for his kids does, so he has a colonoscopy. But first he gets a preview of the procedure in his dreams. That's where Rawls—as a singing doctor—comes in. (TV Guide)
