Played by Jeff Garlin, Jeff Greene is Larry's friend and manager who doggedly sticks up for him and gets involved in his schemes, no matter how morally dubious they may be.
Jeff often involves Larry in covering up his marital infidelities and hiding his pornography. Jeff, although loyal to Larry, will comfortably act the innocent in a confrontation.
Where Larry generally tries to do the right thing, Jeff seems to take a more selfish pragmatic approach. It all makes for plenty of awkward Curb Your Enthusiasm moments.
Susie: Well it was a bike, technically.
