the kitchen test

Republican senator George Voinovich ("known as a maverick") has come out against the nomination of John Bolton as UN ambassador, claiming that he doesn't feel Bolton would pass "the kitchen test," i.e. would you want to hang out with this person in your kitchen? Now it could be argued that passing the kitchen test should not be a qualification to work at the UN, but I think Voinovich was very honest about what actually goes on in many hiring situations. I can think of a few people with whom I've worked in the past that should have been required to spend some time in a kitchen before they were hired.
