A fowl flew overhead and the surgeon jumps up, yells "DUCK!", and fires a round precisely between the duck's eyes. The duck falls to the ground, dead.
A while later, another fowl flies overhead and this time the Interist jumps up and yells "DUCK. Rule out pheasant, rule out quail!" Fires one round into the birds wing. Wounded, the bird plummets to the ground and dies on impact.
Shortly thereafter, another bird flies overhead. The Family Practice doctor jumps up with a shotgun and starts firing buckshot all across the sky. Loaded with buckshot the bird falls to the ground dead. Looking at the carcass, the family doctor says,"I dont know what the hell it was, but I got it. Let's come back next week."
