Back in the day you actually had to bring the cows in and individually pull on each teat by hand for 20 minutes x 4. x however many cows you were allotted. Today you press a few buttons and the cows go through an automated assembly line. Or disassembly or whatever.
Carnation milk best in the land
comes to the table in a little red can
No teats to pull, no hay to pitch
Just punch a hole in s the sonofabitch
