It's a beautiful day and Sophie is hanging her washing on the line to dry when her neighbour, Ethel leans over the fence and asks Sophie how she manages always to hang out her washing on good, sunny days.
Sophie: Well, it's my boyfriend Ernie. When I wake up in the morning, and if Ernie's "old man" is lying to the left, I know it's gonna rain, so I don't hang out my washing.
And if it's lying to the right, I know it's gonna be sunny, so I know I can hang out my washing.
Ethel: And what if it's sticking straight up?
Sophie: Who the hell wants to do laundry on a day like that?
Ta da!
