Pinky Lee was the star of a children's TV show in 1954 and 1955. His catchphrase was "You make me so mad!" The Wikipedia page on him notes that he collapsed on-air later in 1955, which the audience of children had assumed was part of his goofy act. This basically ended Pinky's role on the show, although contrary to rumors at the time he didn't die until 1993.

By my reckoning, this is the first time Linus has ever had an attack due to the absense of his blanket. Lucy's attitude towards her brother's flannel dependence varies from warmly supportive to fierce antagonism.
