Forget Something?

So this guy goes to a pub after work and commences drinking. Later that night he checks the time and knows his wife is going to kill him if she catches him coming home this late. He stands up from the bar and promptly falls to the floor. Still imagining his wife's displeasure, he army crawls, pulling himself along by the arms. He makes it into bed and his wife was never the wiser. When he awakes, he sees his wife standing by the bed, with her arms crossed and not to happy. She says Patrick you left your wheelchair at the Pub again.
