Any Wednesday (1966)

Jane Fonda stars as the mistress of a wealthy philanderer who visits her on Any Wednesday (1966). Ellen Gordon (Jane Fonda) has been a kept woman for the past two years, living in an apartment provided by adulterous businessman John Cleves (Jason Robards). But a mix-up in travel arrangements results in John’s secretary sending a potential business client, Cass Henderson (Dean Jones), to Ellen’s place thinking that it's a vacant executive apartment. The well matched Ellen and Cass quickly hit it off, until that bumbling secretary does it again by telling John’s wife Dorothy (Rosemary Murphy) about the apartment.There was no nudity called for in the script but Boobarella . . . er, Jane Fonda manages to slip a puffy-tipped pyramid out of her top at the 32-minute mark. Any Wednesday will give you a happy hump day!
