Skype is a form of cybernetic telecommunications in which both participants are able to see up one another’s nostrils. It was invented by a Norwegian, Torkin Dreivel, (‘skype’ is Norwegian for ‘nose’) and although considerably cheaper than conventional phone calls, has the serious disadvantage of being able to see the reactions of the person to whom you are talking.

Skype is also a satellite TV channel offering 24-hour exercise classes.
