It turns out Yeager's 17-year-old daughter is dating a 20-year-old guy. When Cade threatens to call the cops on him, he decides to prove he's not a creep by promptly whipping out a copy of the Texas laws concerning statutory rape, which he keeps laminated in his wallet. He then proceeds to explain how the Romeo and Juliet law lets him legally date a minor. Keep in mind, this fellow's not a Decepticon or anything; he's supposed to be one of the good guys.
There are a few levels of weirdness here. For one, wouldn't it be way easier to just have Yeager's daughter be a legal adult, thus negating the need for an entire scene focused on statutory rape in a movie based on a line of small plastic children's toys? Also, considering some of the stories about Bay, including this feels a tad bit like the Hamburglar interrupting your Happy Meal to wax poetic on exactly how he sexually gratifies himself after a successful hamburger heist. (He diligently makes love to a giant pile of purloined sirloin.)
