"The Windy Day" joke

George set out on a very windy day to see his friend Sam who was sick in bed. Hours later, he pulled his weary body into Sam's house. Sam asked him how it was. ''I'll tell ya, it was just brutal. For every step I took forewards, I fell back two steps.''
''Then how ever did you make it over here?'' Sam asked.
''Well, finally I gave up, so I turned around and headed for home.''
