The number 2.7182804... is suspiciously close to Euler's number e (2.71828...), one of the most important constants in mathematics. The equation pretends to be a coincidence, but it's basically saying "look, I raised 1 to a million and somehow got e!"
This is actually a mathematical in-joke because as n approaches infinity, (1 + 1/n)^n converges to e. So 1.000001^1,000,000 is essentially calculating e through the back door. The conspiracy theory vibe of "Coincidence? I think not!" makes it even better - as if the universe is secretly plotting with mathematics.
