No Fatty
I have to say; this dad joke is a real gut-buster. I mean, who doesn’t love a good pun? And this one’s got it all: a clueless patient, a straightforward doctor, and a classic play on words. You can practically hear the dad’s dad laugh echoing through the exam room.

But seriously, this doctor’s advice seems a little extreme. I mean, can’t the guy eat anything? What about salad? Or fruit? Or…okay, never mind. I can see why the doctor just gave up and went for the punchline. Let’s just hope the dad in this joke has a sense of humor – and a good supply of non-fatty snacks!
