Bulbous Jokes

A camel decided to educate his son who she suspected was getting a little inquisitive.
`Mum, why do we have two humps?` asked the son.
`That is so that we can go for days and weeks without water. We can store it in the humps.`
` Then why do we have very long eye lashes mum?`
`That,` he was told, `is to protect the eyes from the sand in a sand storm.`
`And why do we have bulbous looking feet?`
`That is so that we can travel twice as fast through the desert.`
`Mum,` wispered the young camel, "Now I can understand, humps to store water, long eye lashes to protect eyes from sand storm and bulbous looking feet to travell fast in the desert, then what the hell are we doing in this zoo?`
