Call your mother.
(Thanks to Brian Stack for this one - I'd never seen it on video. So, so funny.)
Conan writer and past Sound guest Brian Stack was a 19-year-old intern at a community TV station when he made this eight-minute profile of Del Close in 1986. Close, if you don't know, remains the great hero of long-form improvisation. Stack accidentally set the camera to black and white, so the whole thing has an oddly artsy look. A remarkable and irreplaceable artifact.
