In the proud tradition of naming one's offspring after entire football teams, or a favourite brand of supercar, one US dad has decided to name his son after a software upgrade.

Jon Blake Cusack and wife Jamie, of Holland, Michigan, will certainly be spending many a sleepless night debugging little Jon Blake Cusack Version 2.0 and - in about 16 years' time - having a very hard time explaining to their unfortunate offspring whose bright idea this was in the first place.

Mr Cusack insisted to the local media that his male friends found the moniker "cool", but admitted his wife and her associates were less impressed. Indeed, Jamie Cusack held out for months against the plan and we reckon she will have something to say about hubby Jon's insistance that Version 2.0's first sprog will be Version 3.0, and so forth.

Of course, this type of numerical sequencing of kids is not without precedent: plenty of Romans were called Septimus and Decimus. No Roman, however, was ever burdened with the title Tiberius Augustus Pentium III, and God help the third child of Jon Blake Cusack Version 1.0's fifth son if this madness is not stopped now. ®
