The final season of How I Met Your Mother is under way, which means it's time to cram in a bunch of fun stuff from the series. One of those things will be Bryan Cranston. CBS announced today that Cranston will reprise the role of Hammond Druthers, Ted's former asshole boss from season two whom Ted eventually fired. How exactly he'll be involved in Barney and Robin's wedding isn't exactly clear. Maybe he'll provide the something blue.
