Mr. Johnson is a Muppet character on Sesame Street. He is Grover's regular customer at Charlie's Restaurant and other restaurants as well. Johnson is a fat Anything Muppet who has become increasingly frustrated over the years with the service Grover provides (in earlier skits, Mr. Johnson was calmer and Grover was the one who would get irritated, but the situation reversed over the years). Mr. Johnson is always called "Sir" politely by Grover. Mr. Johnson was mainly performed by Jerry Nelson, and is mostly seen as a customer at Charlie's Restaurant.
