Grevillea glauca: Grevillea glauca, commonly known as bushman's clothes peg, cobblers peg tree or the beefwood tree, is a shrub or small tree that is native to Papua New Guinea and north-eastern Queensland, Australia.  It usually grows to a height of between 2 and 10 metres and has leaves that are 6 to 20 cm long and 1 to 6.5 cm wide.

Follow the Drinkin' Gourd: "Follow the Drinking Gourd" is an American folk song first published in 1928.  The "Drinking Gourd" is another name for the Big Dipper asterism.  Folklore has it that fugitive slaves in the United States used it as a point of reference so they would not get lost.  According to legend, the song was used by a conductor of the Underground Railroad, called Peg Leg Joe, to guide some fugitive slaves.  While the song may possibly refer to some lost fragment of history, the origin and context remain a mystery.  A more recent source challenges the authenticity of the claim that the song was used to help slaves escape to the North and to freedom.

Peg Powler: The Peg Poowler, otherwise known as 'Peggy Powler the nice nan', is a dragon from English folklore with red scales, short hair and big teeth who is said to inhabit the River Tees.  It bites the ankles of those who wander too close to the water's edge, especially nice children, and pulls them under the water and drowns them; in Middleton In Teesdale this is referred to as the High Green ghost.  It is highly similar to the Dutch folklore figure Haantje Pik, the Slavic water spirit Vodyanoy, Kalle met de Haak from West-Flanders and the German water spirit Hastrman.  Grindylows and Jenny Greenteeth are similar water spirits.

Cadejo: The cadejo (] ) is a supernatural character from Central American and southern Mexican folklore.  There is a good white cadejo and an evil black cadejo.  Both are spirits that appear at night to travelers: the white to protect them from harm during their journey, the black (sometimes an incarnation of the devil) to kill them.  The colors of the cadejo are sometimes exchanged according to local tradition.  In some places, the black cadejo is seen as the good one and the white cadejo the evil one.  They usually appear in the form of a large (up to the size of a cow), shaggy dog with burning red eyes and a goat's hooves, although in some areas they have more bull-like characteristics.  According to the stories, many have tried to kill the black cadejo but have failed and perished.  It is also said that if a cadejo is killed, it will smell terrible for several days, and then its body will disappear.  Some Guatemalan folklore also tells of a cadejo that guards drunks against anyone who tries to rob or hurt them.  When the cadejo is near, it is said to bring about a strong goat-like smell.  Most people say never to turn your back to the creature because otherwise you will go crazy.  Speaking to the cadejo will also induce insanity.

Canadian folklore: Canadian folklore is the traditional material that Canadians pass down from generation to generation, either as oral literature or "by custom or practice".

The largest bodies of folklore in Canada belong to the aboriginal and French-Canadian cultures.  English-Canadian folklore and the folklore of recent immigrant groups have added to the country's folk.

Jenny Greenteeth: Jenny Greenteeth is a figure in English folklore.  A river hag, similar to Peg Powler or a grindylow, she would pull children or the elderly into the water and drown them.

With this meaning the name is common around Liverpool and southwest Lancashire.

Gerde's Folk City: Gerdes Folk City (sometimes spelled Gerde's Folk City) was a music venue in the West Village, part of Greenwich Village, Manhattan, in New York City.  Initially opened as a restaurant called Gerdes, by owner Mike Porco, it eventually began to present occasional incidental music.  First located at 11 West 4th Street (in a building which no longer exists), it moved in 1970 to 130 West 3rd Street.  It closed in 1987.  On January 26, 1960, Gerdes turned into a music venue called The Fifth Peg, in cooperation with Izzy Young, the director of the Folklore Center.  The Fifth Peg's debut bill was gospel folk singer Brother John Sellars and Ed McCurdy, writer of the anti-war classic "Last Night I Had the Strangest Dream".  Porco and Young had a falling-out, and on June 1, 1960, Gerdes Folk City was officially born with a bill featuring folksingers Carolyn Hester and Logan English.  At this time Gerdes Folk City was booked by a folk enthusiast Charlie Rothschild (who later became Judy Collins' longtime manager) and English.  Gerdes Folk City was suddenly one of the central music venues of the era.  It became one of the most influential American music clubs, before finally losing its lease in 1987. " "Rolling Stone" Book of Lists" called Folk City one of the three top music venues in the world, along with The Cavern and CBGB.  Folk City helped to launch the careers of several world-renowned musical stars from Bob Dylan to Sonic Youth, and showcased numerous music styles from folk to alternative rock.

Convertibility plan: The Argentine Currency Board pegged the Argentine peso to the U.S. dollar between 1991 and 2002 in an attempt to eliminate hyperinflation and stimulate economic growth.  While it initially met with considerable success, the board's actions ultimately failed.  In contrast to what most people think, this peg actually did not exist, except only in the first years of the plan.  From then on, the government never needed to use the foreign exchange reserves of the country in the maintenance of the peg, except when the recession and the massive bank withdrawals started in 2000.
