Another joke, you say*?

A room-temperature super-conductor walks into a bar and the barman says, “We don’t serve room-temperature super-conductors here.” so the room-temperature super-conductorleaves with no resistance.

If you go watch the video on Boing Boing I’ll stop repeating the jokes here**.







*No-one has said this. I’m assuming it is being thought though.
**This may be a lie.
