Sherlock Hemlock

Sherlock Hemlock (who calls himself "the world's greatest detective") is a Muppet character on the PBS series Sesame Street. His catchphrase is "Egad!" which he exclaims whenever he makes a discovery. Sherlock Hemlock was performed by Jerry Nelson. Prevalence on the show While Sherlock Hemlock made frequent appearances on the show in the 1970s and 1980s, in recent years he has been phased out in favor of newer characters. However, like Lefty the Salesman, Guy Smiley, and The Amazing Mumford, he is still a main character on Sesamstrasse, the German version of the show. Name and appearance
