My Mom's cow story
Not really an "attack," but it seemed amusing to me when I heard it as a kid.

Back in the day when my mom was a kid, most of the part of southern California where she lived was farmland and when she walked to and from school she passed a lot of dairy farms.

One day, she and a friend (cousin?) were walking home when they suddenly found their path blocked by a large cow. While they had seen cows before, they were always at a distance so my mom was quite unprepared to see such a large animal up close.

The cow just stood there, and while it was probably harmless my mom was reluctant to try and get it to move as it was a freaking huge animal with big hooves. I'm not certain, but I think she also said it started to pee at some point, which only unnerved them further.

They waited, stuck in that spot for almost 20 minutes until a friendly farmer came around and "shooed" the cow away. I can only imagine how her family laughed at her when she got home...
