Had been like that for nearly a year. A few minutes of work brought out client js file from 12MB to less then 1mb.
Most often I use unicode strings in unexpected alphabets (i.e. from languages that are not supported by our application and that are not used by the mother tongue of any developer from our team). This includes Chinese, Malayalam, Arabic and a few more. There was a time when I wanted to test the "wrong data" cases for some deserialising function, and I was part annoyed and part amusingly surprised to discover that doing Integer.parseInt("٤٣٠٤٦٧٢١") in Java does parse the arabic digits correctly even without specifying any locale.
Is that a library? Or the string "Chuck Norris"?
I also had a customer discover a playboy center page at the end of a test we sent to them. One of the dev thought it'd be a nice reward. Things went very bad from him right after the phone call...
Had someone at work mention they needed to drop off a dog at grooming on the way to pick up Chinese.
I had to walk away for a bit, as I couldn’t hold it in, but didn’t know if that sort of humor would fly with that crowd.
It certainly caught my attention.
