Plenty Funny Deeds Days are inviting to do funny deeds, causing funny alternations throughout the year. These mostly unofficial holidays sometimes have a concrete origin, like Towel Day, but often they are just for fun. Who likes to join in will certainly have funny topics of conversations on National Tell-a-Joke-Day und make new friends on Wave-all-your-Fingers-at-your-Neighbour-Day. None of these Funny Deeds Days asks anyone to harm anyone.
