After you attend the Rally to Restore Sanity/March to Keep Fear Alive on October 30th, you may want to stay in that night and watch Jon Hamm host Saturday Night Live for a third time.  The show always uses Hamm effectively and has yielded great sketches such as "Don Draper's Guide to Picking up Women" and "Sergio".  Hamm is the latest in a line of host that has me saying "Don't waste this talent, SNL".  Previously announced hosts for the new season include Amy Poehler (Sept. 25th), Bryan Cranston (Oct. 2nd), Jane Lynch (Oct. 9th), and Emma Stone (October 23rd).

Hit the jump to check out some past Hamm sketches. [THR]
