I had this one on numerous o Casio s with students asking what I was on about. That they had 'done' their homework I pointed out that a machine had completed it for them, suggested they give their homework to their 6 year old brother or sister or any other child on their road who can use Google. I then told them about our Deputy Principal who used Google Translate to inform parents of some Newcomer students that their child would be suspended if they did x again. When we double checked the translation it was informing parents their child would be hung for any recurrence. Drastic measures in our schools these days. In the end I got so fed up I showed them the pitfalls and showed them how to at least check for alternative translations: I bought a new coat = J'ai acheté une nouvelle couche. They were gobsmacked when they realized they knew the alternative 'manteau'!
