A woman is milking a cow when an angry bull busts loose and goes charging across the field straight for her.
A farmhand sees what is happening and starts yelling and waving his arms to warn her. The bull is charging, the farmhand is screaming his head off, but the woman just keeps milking the cow. At the last moment before she is trampled and gored, the bull checks up, lowers his head, and skulks off in another direction while she keeps on milking.
Seeing this, the astonished farmhand runs up and says, “Wow! I thought you were dead for sure! Weren’t you afraid of that bull?”
And she says, “I would have been, but this cow is his mother in law.”
