This isn't the most inventive other use for a peg, pegging up posters is quite close to pegging up washing, but as it is St Patricks Day tomorrow it seems a timely choice to post an Irish pub.
"In the late 1800's, the part of Manchester in which the pub now stands - was known as "Little Ireland", due in the main to the large numbers of Irish immigrant workers living there. However, the area was also home to extreme poverty and terrible hardship and quickly came to be synonymous with all the evils and squalor of unregulated industrialisation for Manchester had by then became notorious for.
It was in this charnel house of blood, sweat tears and tragedy that the pub we today know as the Lass O' Gowrie was born." (from the pubs own website)
