Ouch!(2001)

Robert, yet another in a long line of befuddled middle-aged Frenchmen on the prowl. His sister plans to set him up with her friend Claire, without knowing that the two are former lovers. Claire has just given birth to a child that bears Robert's name - it's not his, but their chance meeting throws him into confusion. Enter Aie/Ouch a young, bulimic waitress-model who believes she is from outer space. (Her real name is Marie-Pierre and is nicknamed 'Aie/Ouch!' by her family because of her crazy behavior). Aie promises Robert adulation unlike he has ever known, but his thoughts are drawn to Claire. Undaunted by his indecision, Aie enters high pursuit - and her offbeat charms begin to take effect. A climactic trip to visit her family seems to have everything resolved, but perhaps Aie will decide to return to her home planet.
