Yes Frasier’s nemesis, Cam Winstead, lived upstairs. He was the black version of Frasier, pompous and pretentious. Cam’s mom and Frasier’s dad pretended they were having an affair just to watch their sons have a meltdown.
My favorite episode is when Niles and Frasier had to learn how to ride a bicycle, because they never learned as kids.
My favorite episode was when the new employee at the radio station was interested in an unknowing Frasier who tried to set him up with Daphne.
