El mujeriego (1964)

Juan is a poor book seller, a student of behavior and psychology of Don Juan, who lives obsessed by women, traffics with Playboys with the kiosk and catcalls to all women who pass by, whether accompanied or not. But he is greatly offended when other men praise his girlfriend in front of him. When he wins the pools (even without liking football) a few days before his wedding, he gets drunk on the bachelor party, the same day he learns he has been awarded, and gets angry with his friends for his dishonest advice on marriage.
