Well, at least someone is using humor in their ads and this one is an appreciated gesture. Hawa Chicken goes for "anyone who rubs us the wrong way, we pluck his feathers" (plucking feathers is a local expression to indicate strong revenge). If war taught me anything, there's nothing wrong with laughing at serious situations - if they're good it's appropriate, if they're bad, laughing will make you get through them. And yes, there's a grammatical error in the headline of this post, but it had to rhyme with "stronger".
