Have you seen the Simpsons episode when they're filming the Radioactive Man film in Springfield? These two chaps are painting black spots on a horse to make it look like a cow and Bart asks why they don't use real cows...
"Because real cows don't look like cows on screen, so we have to use horses"
"Well what if you want a horse, what do you use then?"
"We usually tape a bunch of cats together"
😂
