My favorite Jim Belushi story. (It may well be the only one in existence.)
Belushi, upset with what he heard about the film version of "Wired," went to the producer's office, barged past the receptionist, and trashed the joint.
Still furious, as he left, he told that receptionist, "Just tell him I was here!"
The receptionist looked at him and said , "Who are you?"
