Out of all the Rick and Morty figures the one I'm angry at is Birdperson. It's a great looking figure and the articulation is what I like, but the hip joints are so loose that I can't get him to stand properly 95% of the time.
When the X-men movie came out they released a Professor X figure that had leg articulation but the joints were intentionally so loose that it was impossible for him to stand. It was a clever joke. Here it's just super annoying and makes me angry at a figure I otherwise would have loved.
