Mrs. O’Leary’s Cow alvin May 31, 2016 - 12:35pm

When I work at home I usually turn on the tv in the afternoon to hear some background noise, and I just noticed that there’s an episode of the Medium tv series named Mrs. O’Leary’s Cow. I didn’t know what that referred to, so I just looked it up, and it refers to a cow that legend says started the Great Chicago Fire of 1871.
