Portal and Portal 2 are packed with passive aggressive remarks. One of my favorites:

Well done. Here are the test results: You are a horrible person. I’m serious, that’s what it says: “A horrible person.” We weren’t even testing for that. Don’t let that horrible-person thing discourage you. It’s just a data point. If it makes you feel any better, science has now validated your birth mother’s decision to abandon you on a doorstep.
