Viewers Outraged Phelps not in water with actual, real Shark

U.S Olympic swimmer Michael Phelps DIDN'T race a REAL SHARK in the water?  Really?

People are outraged that Phelps did not race a real shark, both being in the same pool or body of water. RealClearLife:

Michael Phelps Sparks Outrage After Racing Fake Shark.

Viewers who tuned in to watch Michael Phelps race a great white shark on Sunday turned off the television feeling cheated, according to the Washington Post.

[.]  Anyone watching had to wait 57 minutes into the program before an ecologist revealed that sharks don’t typically swim in a straight line.

“Clearly, we can’t put Michael in one lane and a white shark on the far lane. We’re gonna have to do a simulation,” said ecologist Tristan Gutteridge, one of the scientists on the much-hyped Discovery show. 

It took an ecologist to inform The Gullible Masses that sharks don't swim in a straight line?

A few Twitter reactions about the fake shark - Phelps race, published in The Jeff Bezos Daily Excrement:

    "I honestly feel so robbed that I just watched an hour of a stupid show to see Michael Phelps race a FAKE shark." #fakenews

"Robbed"?  "Crazy"?  "Incredibly Stupid" and "Gullible" are the descriptions that pop into my mind.

Who are these people who believed this?
