I’m most certainly one of the nerds, having been soldering together memory and I/O boards for my Apple II back in high school in the early '80s. (In our Science and Science Fiction club we met both Carl Sagan AND William Shatner!) I watched a bunch of the Tom Baker episodes back in the day, and a bunch of the new ones.
I’m not sure how mocking Sharknado translates to “mocking the nerds.”
