There’s an ethnic joke there. “She’s a gooda horse but she no look so good.” Apologies to the Italian side of my family and especially to the Sinatra family.
Kinda like the scene in BLAZING SADDLES, where the cowpoke slugs a horse and knocks it down.
I’ll never be your beast of burden
My head is hard but it’s a-hurtin
Looks really beat and myopic.
Poor horse looks sad…
