"The Other Guy"

Fonzie gives Roger questionable romantic advice, and then it turns out he's the title character.  Meanwhile, both Howard and Chachi are accused of no longer being romantic by their respective sweeties.  And the stuff with the dad and the dog is just weird, so C- again.

Notes:

• Howard had an Army buddy come up with poems to send to Marion twenty-five years ago, when they were still single.
• The friend now writes for The Munsters, which debuted in '64.
• Joanie and Chachi watch Gidget Goes Hawaiian (1961) and the TV-movie Gidget Grows Up (1969), both on TV.
• Louise Bryant didn't write anything for HD, but Nancy Churnin, who recently played Mrs. Giles, would do an '84 script.
