My brother and I talked about our favorite artists' television clips. Above is my favorite, and below is his.
The Dali clip is the only commercial Salvador Dali ever made, for Lanvin Chocolate. Never ceases to cheer me up.
Below is one of many Andy Warhol interviews in which Warhol only answers yes or no to every question the interviewer asks. My brother specifically remembered one where Warhol offered to talk in a robot voice and proceeded to do so for the rest of the interview. This clip, though, is short and satisfying.
