"Three on a Porch"

This is another one I vaguely remember, but I'm going with a C+ because of mild racism (against American Indians, while the "Uncle Tom's cabin" joke is arguably literary) and of course sexism.  I do like the "foreign" rendition of "Rock Around the Clock" (a semi-in-joke) and Richie's "mature businessman" voice.

A few notes:

• Now I wonder what Marion did in her college days, besides study Archaeology, as we learned on the episode where Howard wanted to run off to Tahiti.  Sounds like things got pretty wild in the woods.
• This is set during "Easter break."  Come on, timeline!  It's like you're not even trying.
• I wonder if Richie and his pals would've done better if they just tried to pass as college students.
• A rare instance of Fonzie cluelessly cockblocking, although it works out after all.
• Boswell's writing partner this time is Tiffany York, who's only other IMDB credit is a Welcome Back, Kotter episode, from the previous month.
