Rivers of Buckets 

show of exasperation, frustration; phrase indicates agitation and/or sorrow. The phrase came to be in early 19th century Germany when Wilhelm Schwarz could not cross his hometown river because an anomaly of buckets appeared in the waterway. Term became slang in modern Germany (Fluesse Eimer!) and has thusly spread to the world.

Rivers of buckets, I left my child in the attic!
That's such a load of rivers of buckets!
