A poll-taker asked a young housewife what form of birth control she and her husband used. 'We use the bucket-and-plate method,' replied the Woman. 'Umm, I'm not familiar with that method,' the poll-taker replied, 'Could you explain it to me? 'Well, it works like this. My husband's shorter than me so he has to stand on a bucket when we make love.' 'I see,' said the poll-taker, still confused, 'And what happens then?' 'And when his eyes get as big as plates,' the housewife continued, 'I kick the bucket out from under him!'
