Wouldn't have worked. For example in Chinese many double meanings come from the similarity in sound of words, something a dictionary would never be able to pick up. So youd be crippled trying to guess which words it relates to without knowing which words it has a false friend. Despite that, your achievement is impressive. Nothing feels better than making a pun or beating a local in their own language!
