Grazie... nonna (1975)

In the outrageous taboo comedy Grazie nonna (1975), a young Italian boy is dismayed to discover that he’s expected to pick up his deceased grandfather’s widow at the airport. The boy’s feelings quickly brighten, however, when he realizes that his lecherous gramps tied the knot with an unbelievably hot young beauty. French-Algerian bombshell Edwige Fenech plays the grandmother-in-law who’s anything but grandmotherly. As the forgivably horny youngster peeps through keyholes at his knockout nana, Fenech drops her towel to showcase some stunning curves.
