So, one time Adam bought himself and Ben a case of ST:TNG Portfolio Prints Series One cards, because what a pal, right?
And then Adam and Ben decided to also start opening packs prior to the episode reviews.
Sometimes it's just Ben opening a pack, and then describing his glorious cardboardy spoils, and sometimes both Adam and Ben do it at the same time. Occasionally they have found signed cards amongst the episode-centered cards, which spurred on the fruitless hunt for a Natural Yeager.
Ben and Adam discovered that Series One only covers odd-numbered cards, and so when they finished their Series One boxes, they purchased a pair of Series Two boxes in order to complete their super nerdy sets.
With Series Two, the fellows have decided to simply open packs until a limited edition card (i.e. signed card, or the like) is found, creating a competition that is perhaps not terribly well thought out, but is enjoyable all the same.
It was suggested that viewers with ASMR might enjoy this segment a bit too much due to the crinkly sounds of the packs being opened.
