That first bit with Brian was a reference to the movie Dazed & Confused with that character portrayed by Matthew McConaughey. One of the most famous lines from the movie was delivered in that scene, "That's what I love about these high school girls, man. I get older, they stay the same age." Actually, Wooderson (McConaughey's character) had most of the best lines in that movie. Complete scumbag character, but you love him anyway.
