S1·E20 Ghosts and bagpipes

When three red-headed hulks wearing kilts and Scots berets muscle into O'City's saloon bar, Luck Luke chokes on his lemonade! This reaction sets off an brawl, giving the local Irish a perfect excuse to try and knock the brains out of the new lads in skirts. Later, when Lucky Luke is invited to stay at the Scots' castle, he finds himself embroiled in an intrigue involving the McCloud clan, the local Irish and native Indians. He'll have to deal with Lord Bloody's ghost, make peace with the Great Spirit of the Plains, and keep the Indians peaceful with the unexpected help of a Rugby match : child's play for Luke, compared to the next dilemma he's faced with: how to swallow haggis with dignity!
