'Towel thrown in...'

I've always had many laughs and grins at this scene over the years. I as fascinated by it as a little kid, after seeing it in the theatre. If u watch it in slow motion, u notice that Dennis is wearing grey sweatshorts as the cab drives away. Does either the screenwriter or Quaid have a copywright on that visual gag? I've never seen it depicted on film before or since. The closest was a scene in a premium-cable movie where a guy loses it as he climbs the side of a building.









LYD-I-A-HUHHHHHHHHHHHHHH!!!!!!!!!!
