Certainly! Here are the most famous impressions associated with each of the comedians I mentioned earlier:

1. Rich Little - Known for his impressions of many famous personalities, some of his most popular include former U.S. Presidents Richard Nixon and Ronald Reagan, and celebrities like Johnny Carson and John Wayne.

1. Frank Caliendo - Frank Caliendo is famous for his spot-on impressions of former U.S. President George W. Bush, sports commentator John Madden, and actor Morgan Freeman, among others.

1. Jay Pharoah - Jay Pharoah gained popularity on Saturday Night Live for his impressions of various public figures, including former U.S. President Barack Obama, rapper Jay-Z, and actor Denzel Washington.

1. Harpo Marx - As a member of the Marx Brothers comedy team, Harpo was known for his silent, mime-like performances rather than vocal impressions. He played a character that used props, facial expressions, and exaggerated gestures to communicate, often accompanied by his trademark horn or harp.

1. Charlie Chaplin - A legendary silent film actor, Chaplin is most famous for his iconic character "The Tramp," who was characterized by his shabby clothing, bowler hat, mustache, and cane. Through his physical comedy and expressive facial expressions, Chaplin was able to convey a range of emotions and create memorable scenes in films like "The Kid," "City Lights," and "Modern Times."

While some of these performers were more known for their mime or physical comedy rather than vocal impressions, they all made lasting impressions on audiences with their unique styles and performances.
