Pilot episode--a real curio
Very interesting to see how Hazel character evolved from the frowsy housekeeper of the pilot episode to the efficent up-beat heroine of later shows.
In first episode, she was unkempt looking and behaved in childish, peevish manner, almost like a sitcom version of her Come Back Little Sheba character. Her hair was a mess, she really dragged feet about cooking for Dorothy's birthday (because it was her day off, I believe) and, in most mawkish sequence, even retreated to her room and performed a pathetic exotic dance to a radio song, just like in Sheba.
Thankfully, someone realized this just wasn't funny and show was rapidly inrevamped to the long-running crowd-pleaser it eventually became.
