MENE, MENE, TEKEL, UPHARSIN are funny metaphors if at all.
this one is even funnier if taken as a metaphor :-)
4:33 The same hour was the thing fulfilled upon Nebuchadnezzar: and he was driven from men, and did eat grass as oxen, ----, till his hairs were grown like eagles' feathers, and his nails like birds' claws.
I have talked to reverends and bishops about such things in the Bible and found them invariably dumbfounded.
Most of them do not even know about the existence of Daniel verse 4:33.
