PB&Jeff was a YouTube show on PBGGameplay where Peanut Butter Gamer and SpaceHamster would play games together. It was known for creating many recurring jokes on the now defunct PBGGameplay channel including "I Pressed it to jump", and PBG and Jeff making up odd and comical T-shirt ideas. The series itself was edited mostly by the very cool and very talented editor Jack the Editor.
The last episode was uploaded in 2019. PBG has since stated that he and Jeff have no plans to produce any further episodes of the show
