Worst/ weirdest/ funniest pop culture reference (or easter egg) in a game?

Yes, I heard it was sort of a tradition in LGS to put a hidden basketball course in each of their finished games. And you can find a scroll with the dev quotes in the first two games (one of them being in said basketball course).

System Shock 2 also has a basketball court. And it also uses the same engine as Thief 2
