How I Met Your Mother is ending next week. What are we going to do? Sorry, this is Billy Eichner: HOW I MET YOUR MOTHER IS ENDING NEXT WEEK!!! WHAT ARE WE GOING TO DO!?!? Well, Billy and Neil Patrick Harris hit the street to scream and try to get answers, in a clip from tomorrow’s Billy on the Street. Billy seemed particularly worried for Cobie Smulders. Ahhhh!!!!!!!!!!!!!!
