Re: How I Met Your Mother: Barney and... (Spoilers ahead...)
I liked the Puzzles bit and found it much more interesting than the whole "Mysteries of the Unexplained" bit with Marshall and Lily.
I groaned when Ted mentioned that Robin's career turnaround would be explained later, as that's the problem with the show, everything somewhat interesting is teased and we're told he'll tell us later.
