A Zebra arrives on a farm. The first animal she meets is a cow. "Whats your job?" she asks.
"My job is to give milk," the cow replies.
The next animal she meets is a chicken. "Whats your job," she asks.
"My job is to lay eggs," the chicken answers.
The third animal she meets is a stallion. "Whats your job?" she asks.
The stallion replies, "Just take off those stripy pyjamas and I'll show you."
