How I Met Your Mother: The Musical

The current season of How I Met Your Mother started off a little slowly but things are starting to pick up. First, the old Barney Stinson is back in the action in all of his sex-crazed, woman-hunting glory. Second, the next episode is titled ​“Slapsgiving 2: Revenge of the Slap.”

And third, and most importantly, the 100th episode — ​“Girls Versus Suits” — will feature a musical number by the one and only Neil Patrick Harris. Which, if you’ve seen Dr. Horrible’s Sing-Along Blog, you will be a very, very good thing. (Oh, and my wife will be very excited to learn that ​“Girls Versus Suits” will also feature a cameo by Tim Gunn.)
