Pitch Perfect

There was a lot to annoy the viewer in last night's episode of How I Met Your Mother (how do you write in a dance-off and then have most of it happen offscreen?! Also the usual total non-advancement of the plot). Then producers threw on a tag delightful enough to get us to tune in for at least one more week. DAMN YOU, PRODUCERS, WHY CAN'T YOU MAKE THE WHOLE SHOW THIS GOOD?
