I found this video on YouTube the other day and just have to share it with you. Many characters in TV and film have signature lines or styles of line, just think about the many Arnie-isms you have heard, and that's across lots of different films.
These things are mostly fun for the audience, they are familiar and as such put a wry smile on your face, even when the lines themselves aren't that good. As a writer what you really wouldn't want is someone splicing together lots of them in sequence, thus highlighting how repetitive and stupid they can be.
My heart goes out to the writers of CSI: Miami. The series isn't that great, but no one deserves this. However big props to stewmurray47 for putting this together, very funny. (this requires sound so maybe wait till you get home after work)
