Chi va con lo zoppo impara a zoppicare

Italian: Chi va con lo zoppo impara a zoppicare
Spanish: El que va con el cojo, aprende a cojear
French: Qui fréquente le boiteux, apprend à boiter
(there's no English translation, but this literally means "if you go with the lame, you'll learn how to limp" or something like that")
