Something new and innovative from Berlin: the begging horse. Some guy decided that begging with a horse mask for weed and beer might be more succesful than other approaches.
I can not assess if that works, but in my opinion it makes a funny costume: you just need horse mask and a sign asking for weed and beer. Et voila, the beggar horse costume is complete. A picture of the „prototype“ can be seen at the link below.
