If you’re a Little House on the Prairie fan, you likely remember the first kiss between sweet Laura Ingalls (Melissa Gilbert) and Almanzo Wilder (Dean Butler) on the series. Gilbert was only 15 at the time, and her first onscreen kiss was actually her first kiss in real life, too — something that she wasn’t too thrilled about. Not to mention the fact that Butler was much older, about 23 at the time.
