How I Met Your Dad, the revelatory re-imagining of How I Met Your Mother that takes typical gender conventions, turns them upside down, and then says, "Pay us money, advertisers!" has filled a few new roles.

Greta Gerwig plays Sally (that has been announced already), who presumably sluts it up for like seven or eight years before finding Mr. Right. (This is preferable to Ted's mopey ass staying basically celibate and whining about how he doesn't have a wife.)

Workaholics' Anders Holms will be in teh mix, as will Smash's Krysta Rodriguez (whatever) and Masters of Sex Nick D'Agosta.

Ok. I'm fond of Anders, but unfamiliar with these others. Maybe they could get Zach Galifianakis' brother Seth to do the narration.
