"Not With My Sister, You Don't"

This is one of the best episodes so far, with some laugh-out-loud moments and some heartfelt moments, which somewhat overlap, as in the "sex talk" scene between Marion and Joanie.  And, yes, the irony is thick as Fonzie doesn't seem too concerned about Joanie dating his twelve-year-old nephew Spike, when she'd later date and marry his cousin Chachi.  This also of course is the debut of Richie as protective older brother, which would be a big part of the next five and a half seasons.

Notes:

• I know Tony Randall was then working for Garry M. at Paramount on The Odd Couple, but I was definitely not ready to see him as an untransformed werewolf kissing in a black & white movie!
• Is Carol the first girl to kiss Richie, Potsie, and Ralph?  I like how we can both sympathize with her and understand Richie's sense of honor that requires him to keep ditching her.
• The aptly named Danny Butch would return as Raymond "Spike" Fonzarelli thrice more and he's quite good as Fonzie's mini-me.  I remember preferring him to Chachi, for what it's worth.
• The little bit about "The Code" between Potsie and Marsha is quite good, playing off the by-1974 outmoded rules that girls were supposed to follow about when to accept dates.  (Gidget had an episode about this in '65.)
