One Armed Irishman

One armed Paddy is playing Father Christmas in the full outfit, green suit, green beard and a green toy bag. As he gets on top of the roof, a big drift of snow dislodges him and he grabs hold of a phone cable with his only hand. A passer by notices Paddy and says to his friend, "How shall we get him down?" "Easy" says Jock, "just wave".
