Who has time to be sad when there's so much reminiscing to do?
How I Met Your Mother may be preparing for its last ever episode to air on tonight (March 31), but that doesn't mean we have to bum ourselves out already! There have been a million great moments on the show, not least of all the dozens of musical acts put on by the cast.
We'll never forget Robin Sparkles' famous throwback numbers or Barney's classic holiday songs. And what about that time the entire crew got together to perform the show's theme song? There are too many to count, so for now let's just stick to the top 12 and go from there.
