Sherlock Holmes was the first to point out how little most of us really observe about our surroundings. This week on WireTap, Jonathan tests Tucker's perception skills with a pop quiz...about the minute details of his own apartment. Also, Starlee reunites with her 15-year-old personal intern and Gregor tries to convince Jonathan to leave the hustle behind and take some dance lessons. That's WireTap, with Jonathan Goldstein, Sunday afternoon at 1 (1:30 NT, 4 PT) on CBC Radio One.
