Cow Tools is definitely out there. I didn’t get the joke fully although the idea of a cow standing on its hind legs making tools is fairly amusing.
Someone gave me a Farside book as a teenager and I absolutely loved it. Gary Larsen is a genius.

One of my favourites is the picture of the guy reading a note and a car with two grinning dogs in it driving away. The note says:

"Master, Me and Rex took the kar to town. Stay home.
STAY!!!
Ha Ha Ha Ha
the dog"

Cracks me up every time. 😁
Thanks for this story, Hogan. I need to go and dig out that Farside book now and give it to my kids.
