In the late 90s, DOS-era, I was working on a simulation in Matlab. Something just wasn't working right - as per the limited docs. Getting very frustrated, I typed "f_ck you" on the matlab prompt. It came back with "Your place or mine?". This was so unexpected, I burst out laughing. Definitely released some stress. I went looking for how this worked: turns out matlab had a "command" called "f_ck" and it had 10-something fixed messages as responses hard-coded into it. It would return one of these randomly.
