I encourage you all to live life on the wild side and answer in an alternative fashion, especially if it's an unknown number.

This only backfired on me once years ago when I'd applied for some jobs and I answered ridiculously, only to realise it was one of them. They didn't know what to make of it. I tried to pretend like nothing happened. They played along for the duration of the call, but never contacted me again.

I'm content in my job for the time being and nobody really EVER calls me in an official capacity so I'm free to enjoy the wonders of having fun with telephones
