Beelzebub (b) won a trophy cup (杯) for his amazing Christmas tree (木). Actually, it was forbidden to log trees in front of the Eiffel Tower (ei1); but Beelzebub didn't care and took the tree anyway. He even took the forbidden sign (不) as well, and as he receives his trophy cup he uses the forbidden sign as a tablet to put the trophy cup on.
