And the cat named Cortana.
The number is more an imagined thought; more that there are six people in the same family named Jeff. No special identifiers like Jr, Sr, DDS or ICQ.

So like this.

Just googled out of curiosity. In India you have to

1. Submit an affidavit notarized and signed by two witnesses on a stamp paper / official paper of required value (notary fees+stamp paper cost will be less than Rs.1200 / $20)

2. Have the name change appear in one regional language and one English newspaper (cost varies so lets assume Rs.500+500 so again less than $20)

3. Pay for and have the name change appear in a Gazette (costs around Rs.900 so again less than $20)

Then you can finally have the pleasure of changing your name on every official documentation and ID, cell phone number and bank account through their own individual procedures.

Yup we would be savages without this red tape.

easier and cheaper to change your name than correcting a booking mistake by Ryanair

"A student has changed his name by deed poll because it was cheaper than paying a “ridiculous” Ryanair charge for a booking error."

This thread reminds me of an old joke from the DDR (GDR) era:

In East-Berlin, a man enters city hall, requesting a name change.
The registry clerk asks him why he wants to change his name, and the man answers: "Well, my current name is Erich Schlappschwanz (transl.: Erich Limp-dick), so I'm sure you'll understand why?"
To which the registry clerk replies: "Ah yes, I see...who wants to be named Erich, huh?"

;)

And that reminds me of all those ancient Unix annunciation jokes, where they'd all center around Eunuchs.

Did you get my awesome pun? Jeff3 => Jeffrey => rimshot => hysterical laughter.

I'm afraid something was lost in translation.

Its the state job to prevent this, this is one of the reason one is paying taxes.

Okay, but why is it the state's job to prevent name changes? What if your mother was unkind and named you after an unconventional figure, leading all the farmers to stare at you at contempt?

So I actually underwent surname change due to parents and its done by similar subdivision that does it during the birth (some registrar agency thing). They will basically deny it and if you argue, you'll have to go through court, which is also state division, so the law takes priority over personal freedom. AFAIK nicknames are not affected by this, but offensive nicknames for kids will fall into bullying, so if one is over 18/21, then state sees him old enough to let him care about own stuff so long it doesn't endanger the public afaik. I don't think farmers are endangered by the unconventional nickname so they can collect all the contempt they want and let it out in their tractor's cabins :)

Erich built this. How many factories did you built?

Presumly this jokes originates from Public Law 80/402 disinformation agencies. Its easy to spread jokes when you got nothing destroyed, nobody killed and 2/3 of world gold of dubious origin came to you. Maybe you forgot the Dresden events.
