idiomsphrase-requests

For an example, I'll quote C.S. Lewis' The Voyage of the Dawn Treader:

One day the cat got into the dairy and twenty of them were at work moving all the milk out; no one thought of moving the cat.

An overly complicated device could be a Rube Goldberg machine. This could be used for a metaphorical machine as well, or one could use Rube Goldberg process.
