Legend has it that many many years ago, in Ireland, there lived a giant called Finn McCool. One day as Finn was going about doing his daily routine, A Scottish Giant named Benandonner started insulting Finn from across the channel. This infuriated Finn and from where he was standing, he picked up some earth and threw it (across the channel)at the Giant, but the earth landed in the sea.
In response, the Scottish Giant, threw a rock at Finn and shouted that Finn was lucky that he was not a strong swimmer as he would have swam across the Channel to deal with him. This made Finn livid and he began throwing huge pieces of earth making a causeway so that Finn could cross over the channel to confront Benandonner. Instead, Benadonner crossed the Channel and went to pay Finn a visit.
When Finn saw the size of his Scottish counterpart who was somewhat bigger than him, he became terrified and ran inside his house and came up with a canning plan. He dressed as a baby and pretended to be asleep. When Benandonner came inside the house, Finn's wife told him that her husband was away and that she was alone with her baby son. When Benadonner saw the size of the baby he became petrified. If the baby was this huge, he thought to himself, then how big was his father? He ran out of the house and across the causeway, breaking it up as he went along, hoping that the two Giant's paths would never cross again.
