Question:In the black and white second season Dick York as Darrin episodes and the color Dick York as Darrin episodes,did they mention the fact that Aunt Clara collected doorknobs?Or did they only mention that in the season one Black and white Dick York as Darrin episodes?

No - Aunt Clara's love of doorknobs was mentioned in the color seasons, too. Marion Lorne actually collected doorknobs in real life!!!! :cool: :D
