Okay, I'd like to know more.

Some variants featured 'breaking a child's arm'

Also, "Enjoy a new career fouling canal paths and filter-feeding in municipal waterways!'

One place had the sign in the window with "Or pop in and ask about a job here..."

Quote from an article about it:

> One person joked: “Well damn, I've just been s***ing on canal towpaths on an amateur basis, I didn't realise there was a career opportunity to be made out of it.”

Brits left giggling at unusual job advertisement offering 'retraining as a swan'

The funny job vacancy was posted in the window of an establishment in Tintagel, Cornwall, and it offered people training in 'gliding serenely' and eating bread

@xinit
Is the salary paid in stale bread?
@xinit Shades of Fokawolf methinks
@xinit it’s just the one day, actually

@xinit

A Viz classic, innit?

@xinit beats a job in cyber
@xinit "Getting eaten by monarchs"

@xinit
I see they've dropped the - terrorize small children?

Being a swan isn't what it used to be.

@xinit @minx as advertised by U2 in their song Sunday Bloody Sunday:

♫'Coz to-night, we can be a swan to-night ♫

@xinit up to £40 per what?
@edgeofeurope Total. Swans can't really use money anyway.
Swans don't honk, they hiss. Seems like they're luring people in with swan roles but force them to be geese instead.

@xinit

I've been working as a swan for the past six months, and I gotta tell ya, taking this course was the best decision I ever made. No more meetings-that-could-have-been-emails, no more mandatory HR training, no more Terry in accounting with his gawd-awful halitosis and festering sense of 'humor.' I'm finally at peace with my vocation. And the work/life balance is at near Finnish standards! Plus, I get to break arms. Sign up today! cygnusjobs-4-u dot net will change your life!

@saltywizard @xinit Don’t you mean, cygn up today? 
@xinit I love how the domain exists.
@revk @xinit OK so I'm not the only one who checked that. Phew!
@xinit please, it's more useful than my current employer
What's Up with Those Bizarre 'Retrain as a Swan' Posters?

Snopes.com

@xinit I signed up years ago, still have not heard back from them.

Might be a hoax, be careful.

Or they may not take applications from ospreys, I dunno.

I'll keep the fishy stuff.

@xinit It certainly sounds more appealing than my initial reading of the text "Want a New Challenge? Restrain a Swan!"
@xinit Reads like an advert in Viz. Do I win £5?
