This contest could be classified as an historical part of practical ranch work.
Most of the cowboys on the open range probably drank their coffee black because adding cream could get you killed.
More than one ranch cook has said,
"The coffee is in the pot, I've got the cream caught and tied to a tree, but you gotta go get it."
The object of this contest is for a team of ranch hands to get enough milk out of a beef cow into a paper cup to pour out in front of the judge.
