The episode where Sammy Davis Jr. guest-stars has to be my favorite, and I'm just waiting for TV Land to air it once more. My two favorite Archie lines from that episode are -

"Sammy, do you take cream and sugar in your eye?"

"Edith, why can't you ever just say 'yeah' and STOP?"

I love the look on Sammy's face when Edith brings him a twinkie.
