Mister Know It All is the annoying person that has to tell you that he knows the best. Mister know it all feel the urge to correct everyone if he believe he is right (wich is very often).
Tim: oh, look at that white cat, it's so cute!
Jim: what white cat? I can't see any white cats here. Oh, you mean the white cat with some grey dots on it's forehead? Cause that isn't a white cat. That is a semi colored cat....

Tim: can We just warm up some noodles night? I feel like eating something easy, the japanese way.
Jim: uhm, noodles are actually chinese and not japanese, just so you know....

Jim is the annoying Mister Know It All in this friendship.
