Haha, yes, if the cucumbers were Russian, then Putin would probably organise a cucumber eating contest or something like that!
Yes, I agree that Russians have a reputation at being a bit wild... In Swedish language it's almost implicit that anything with the prefix "Russian" (rysk) is nickname for something extreme or dangerous... like a Russian jump, Russian Post (very saucy game that kids play, Russian summer/winter and many more.
Apparently Spain is not happy that its cucumers were falsely accused!
