"Tam o' Shanter" is a narrative poem written by the Scottish poet Robert Burns in 1790, while living in Dumfries. First published in 1791, at 228 (or 224) lines it is one of Burns' longer poems, and employs a mixture of Scots and English.
The poem describes the habits of Tam (a Scots nickname for Thomas), a farmer who often gets drunk with his friends in a public house in the Scottish town of Ayr, and his thoughtless ways, specifically towards his wife, who waits at home for him. At the conclusion of one such late-night revel, after a market day, Tam rides home on his horse Meg while a storm is brewing. On the way he sees the local haunted church lit up, with witches and warlocks dancing and the Devil playing the bagpipes. He is still drunk, still upon his horse, just on the edge of the light, watching, amazed to see the place bedecked with many gruesome things such as gibbet irons and knives that had been used to commit murders. The music intensifies as the witches are dancing and, upon seeing one particularly wanton witch in a short dress, Tam loses his reason and shouts, '"Weel done, cutty-sark!" ("weel": well; "cutty-sark": short shirt). Immediately, the lights go out, the music and dancing stop, and many of the creatures lunge after Tam, with the witches leading. Tam spurs Meg to turn and flee and drives the horse on towards the River Doon as the creatures dare not cross a running stream. The creatures give chase and the witches come so close to catching Tam and Meg that they pull Meg's tail off just as she reaches the Brig o' Doon.
