Spalding Gray

MSNBC - Altercation: "Spalding Gray even made his name on Sesame Street, in a way: one of the Monsterpiece Theatre segments parodies 'Monster in a Box.' (The skit is in some ways a retelling of a classic Kermit and Grover skit from the first season of the show.)
Spalding Monster starts on his box, then next to the box, then Alastair Cookie yells, 'You wrote this, and you don't know *in*? Spalding!' and proceeds to put him, forcibly, in the box."
