Check out the poster in the background of the picture. If there were any "Law & Order" character who would be a Thelonious Monk fan, it would be Det. John Munch (Richard Belzer). This shot is from this week's episode of "Law & Order: SVU." Oddly enough, it was aired on what would've been Monk's 89th birthday.
My apologies for the low-quality picture. I don't have any fancy TV screencap devices.
