Duck

[Capt. Zero]

Five doctors decided to go duck hunting the next day together. Early the next morning the MDs (A G.P., a pediatrician, a psychiatrist, a surgeon, and a pathologist) show up at the duck blind with their shotguns. In a little while a little bird flies over.
The G.P. stands up, looks at the bird, then sits down and says, "I'm not sure that's a duck."
Next the pediatrician hops up, looks at the bird, sits down and says,"Well I'm sure that's a duck, but I don't know whether it's a little boy duck or a little girl duck."
Then the psychiatrist stands up , looks at the bird, sits down and says,"Well I know that's a duck, but I don't know if it knows it's a duck."
So the surgeon stands up, looks at the bird, raises his shotgun and blows it out of the sky, sits down, turns to the pathologist and says,"Go find out if that's a duck."

Ditto here.
The host has changed that second link to an add. It went something like this (but done a bit better), and complimented the toon.
