Not sure about other countries, but the Russian branch of Burger King had some uniquely bad sense of humor when it came to their ads. The most known as was a wordplay between "Don't get too spicy" and "Don't shit yourself", but there was another ad of chicken nuggets with a little chick in the corner saying something like "6 nuggets for 99 rubles!". I found it hilarious to see a chick advertising their mom.
