Metaphorically speaking…
I like to think that having a job is like owning a cow: sure, you may be surrounded by manure and a bunch of slow-moving creatures, some of whom may be mad, and you may also have to milk it for all that it is worth, but "hay", at least you have a cow! In a related note, when Bart Simpson says "Don’t have a cow" is he actually, in covert language, propogating the subversion of the current market economy? Hmmm…something to ponder.
