Oscar the Grouch [SEP] Introduction
Oscar the Grouch is a fictional character on the PBS/HBO television program "Sesame Street". He has a green body, no visible nose, and lives in a trash can. Oscar's favorite thing is trash, as evidenced by the song "I Love Trash", with a running theme being his collection of seemingly useless items. Although the term "Grouch" aptly describes Oscar's misanthropic interaction with the other characters, it also refers to his species. The character was originally performed by Caroll Spinney from the show's first episode until his official retirement in 2018. Since 2015, Eric Jacobson has been the understudy for the character, and has taken on the full voice role since Spinney's last time puppeteering him.
