It happens to the best of us. You think you’ve got five extra minutes to play solitaire on your phone, then all of a sudden you’re late for work. So you throw on a blazer, straighten your tie, and comb your hair — all while forgetting to check your clothing for hangers.
Unless this weatherman knew he had to tell the Midwest it’s going to be cold until the middle of July, in which case he might have been hiding the hanger in his blazer to commit seppuku. I’m pretty sure it was just forgetfulness (and solitaire).
