Interossiter

Yesterday at the video store the guy at the counter reads my name off my ID and makes some comment about an 'interossiter'. A few blank looks and explanations later, it turns out that the interossiter was a device from 50's sci-fi movie 'This Island Earth' that the people of earth constructed (following alien instructions) to contact said aliens (a la 'Contact' - but with less Jodie Foster and more running and screaming).

I think the correct spelling is (sadly) interociter, but I'm going to ignore that.

Video store guy: "ok, this needs to be back by Wednesday at 8, but if you're going to be late, just call me on the interossiter".

And I will.
