One of Us: The commentaries feature frequent references to nerdy or geeky activities/interests, unsurprising considering we're their target audience. In the Harry Potter Rifftrax, several jokes were made referencing things that were either only in the books, or hadn't been introduced yet in the films (like a joke involving Horcruxes before the Half-Blood Prince film had been released). In the Lord of the Rings rifftrax, the guys gushed about Middle Earth and its rich history, like Mike giving a detailed explanation of the meaning behind Aragorn's war cry "Elendil!" Video game references are the most frequent and generally occur with the least provocation. Mike makes jokes several times that hint he spent most of his teen years playing NES games, and jokes about more modern video games like Portal get brought up as well, though they have more of a We're Still Relevant, Dammit feel to them sometimes.
