How I Met Your Mother's final season — the one that's going to span the 56 hours leading up to Barney and Robin's wedding — has enlisted The Office's Ellie Kemper for at least one episode. She'll play "one of the most attractive, available, and — as Ted discovers — unfortunate guests" at the wedding. Also set to appear are Wayne Brady (he's Barney's brother) and Sherri Shepherd.
