I once had a "roommate"* for several months that did a ridiculously good Walken impersonation. Like, good enough that if you recorded it and played it back to back with a real Walken recording, it would be extremely difficult to tell them apart.
The problem was, he would do this constantly. Sometimes going days in end refusing to speak normally. I once overhear him dirty talking to himself while masturbating and using the voice. It was awful.
*Very long, funny-in-the-telling type of story that was genuinely fucking awful
I'd never heard of the Cambridge or Princeton commas. Assuming this isn't just a joke and they really exist, they can both go fuck themselves. Also that Cornell, needs to be a semicolon.
