Dr. Frasier Boss is a character played by Jon Daly. In his debut appearance, Dr. Frasier Boss (a.k.a. Kelsey Grammer) is revealed to be Bill Cosby-Bukowski in a mask. The personality of Dr. Frasier Boss is held by whomever possesses the mask. Lord Andrew Lloyd Webber adopts the persona for a time, a horrid experience he describes as "being in a prison."
