A brave explorer is battling through the Amazon When he happens across two natives having a heated argument. 'I'm telling you, it's WOOOMM, with three 'o's and two 'm's! 'No, you idiot, it's WOOMBBE, with two 'b's and an 'e' at the end!' The explorer decides to weigh in at this point, 'Look, chaps, it's actually WOMB, one 'o', one 'm' and one 'b' at the end.' The first native looked to the second. 'How on Earth does he know what sound a hippo makes when it farts underwater?'
