Plot hole: When Butthead pushes Beavis out of Muddy's car, Beavis causes a huge car crash. Then, a few seconds later Butthead falls out and causes cars behind him to crash, but the crash that Beavis started made a barrier along the highway, so how could those cars get behind Butthead so fast?

Plot hole: Why is that shark machine even there? The only reason it's there is to help the plot, and I don't see how it is of use to anyone in the corporate world.

And fishing companies should know better.
