A zebra escaped from a zoo and it hit onto a field full of cows.

The zebra walked up to one and said: 'Hello Love, what do you do around here then?'

'I eat grass all day, and get milked morning and night,' replied the cow.

'Oh,' the zebra said and went over to another cow. 'Hello Love, what do you do around here then?' He asked again.

The cow repeated the same.

The zebra then walked over to a bull. 'Hello,' he said. 'What do you do around here?'

The bull gave him the once-over and said: 'Get those pyjamas off and I'll show you.'
