why did the cow want a divorce?

She had a bum steer.

To understand why the cow might want a divorce, we would need to consider the context and circumstances surrounding cows. As an AI language model, I don't have access to specific information about individual cows or their personal motivations. However, it's worth noting that animals, including cows, do not typically engage in human concepts such as marriage or divorce. These concepts are primarily associated with humans and their social structures. So, in the case of a cow wanting a divorce, it's likely a humorous or fictional scenario rather than something that would occur in reality.
