It almost sounds like the opening line of a joke. A woman and a kangaroo walk into a McDonald's. Well, that actually happened at a McDonald's restaurant in Beaver Dam, Wisconsin.

Police were called to the McDonald's as they responded to a complaint of a woman who brought a kangaroo into the restaurant.

The responding officer says he confronted the woman who had a baby kangaroo wrapped in a blanket and tucked into an infant car seat. She claimed that the kangaroo was a service animal to help her cope with emotional distress and produced a letter from a doctor.

The officer said the woman agreed to leave the restaurant.

McDonald's says its policy is to make restaurants accessible to all customers, including those with disabilities and  special needs.
