Set to retire at the end of the week, legendary news woman Barbara Walters did something over the weekend that she had never done in her 50 year career.  She made an appearance on NBC's "Saturday Night Live."

SNL has poked fun at Walters over the years with great impressions by Gilda Radner, Rachel Dratch, and Cheri Oteri.  But this weekend, the real deal poked fun at herself before her last TV appearance at the end of the week.
