I was over at Half Priced Books the other day cruising the movie books. Picked up an Alfred Hitchcock encyclopedia and started paging through it. I came upon Mr. & Mrs. Smith & there was a funny bit about Carole Lombard being quite the joker on the set. I don't have the exact text in front of me (didn't but the book) but for a while she was sticking a FDR bumper sticker on Bob's car every day. He'd head out at the end of the day and peel the sticker off his car only to have it again the next day.
Remember, Roosevelt was a Democrat & Bob was a staunch Republican/Wendell Wilkie supporter. 'Twas 1940 election time.
Ergh, it pains me to think what car got the sticker slapped on it.
