My favourite is part of the story of the old woman who carried her husband's soul up to Heaven in a leather bag. When she came to an uncrossable river, Mr Blazes (the Devil) offered to put a bridge across it in exchange for the first soul that crossed it. She agreed - and sent her corgi over. Mr Blazes admitted he had been bested, and tried to collect, but the corgi bit him. He swore at the dog ("To Heaven with you!") and vanished in a puff of smoke. She crossed over safely, and she and the dog did the same later when it was time for them to go.

(She also bests St Peter and St Paul but that's another matter)
