Look around. Most mammals have a butt, divided into two cheeks. And if they could stand on 2 legs, their butts would stick out farther than human's. Also common to almost all animals: mouth, nose, 2 eyes, 2 ears, food goes in one end and out the other. We are more alike than we are different, in a physical sense.
I think the word squirrel, with that scritchy sound in there, excites dogs. Even those who do not know what a squirrel is. My lab is 3 yo and he has seen squirrels but always in the "leave it" context and never the word squirrel.

When he heard the word squirrel his ears pricked up and his head tilted.
This is a visual joke so use your hands. Do you know why women have trouble gauging distance? (holding hands about 6 inches apart) It's because men having been telling us this is 10 inches for centuries.
Clicker train your dog. Then use the clicker and reward after bangs. Give the sound a name, like firecracker or bang or boom.

Better to do this kind of thing with a meal that will not kill your dog if he grabs it. Cooked chicken bones can be lethal! Any kind of cooked bone can be lethal. They splinter when chewed and the sharp bits puncture the dog's/cat's stomach and intestines causing a slow, hideous death if a vet can't operate quickly and remove the shrapnel and stitch up all the internal wounds.
It's the top of a purse. The purse material was attached to the little rings around the bottom. The top opens wide enough for a hand to get in. Saw one on Antiques Roadshow and the top, as shown above, was 14k gold and the purse part was 14k gold chain link.
