A flea once said to an ox, 'How comes it that a big strong fellow like you is content to serve mankind, and do all their hard work for them, while I, who am no bigger than you see, live on their bodies and drink my fill of their flood, and never do a stroke for it all?'
'They'd pat me, too,' said the flea, 'If I let them: but I take good care they don't, or there would be nothing left of me.'
