A couple had been married for six years, and their sex life had
 bcome a little repetitive.
 
 The husband suggested that they spice things up by trying a new
 sexual position he had heard about, called 'the wheelbarrow'.
 
 'How does it work ?' asked the wife.
 
 'Well', replied the husband, 'you get on all fours and then I
 stand behind you and lift your legs up to my waist, like a
 wheelbarrow'.
 
 The wife thought about it for a little while before replying that
 she would give it a try on two conditions.
 
 'Okay' said the husband 'what's the first condition ?'
 
 'Well', replied the wife 'You have to promise that we'll stop
 right away if it's painful'.
 
 This seemed reasonable so the husband agreed and enquired as to
 the second condition.
 
 'Well', said the wife 'you have to promise not to go past my
 mothers house'.
