Splash (1984)

In Ron Howard's romantic comedy (and Disney's first Touchstone release):

• the scene of Manhattanite fruit/vegetable wholesaler Allen Bauer's (Tom Hanks) second rescue by a mermaid named Madison (Daryl Hannah) in the waters of Cape Cod
• her arrest for being naked on Liberty Island (at the statue of liberty)
• her screeching pronounciation of her name that shattered store windows
• the sprouting of a tail while taking a bath and having to hide her flipper from Allen
• the scene of the fish-woman's devouring of a live lobster (with its shell) in a restaurant
• their farewell scene when she kissed him before diving back into the water -- and Allen's last-second decision to join Madison underwater forever!
