It's a Grouchy, Grouchy Party

"It's a Grouchy, Grouchy Party" is a song in the 1998 Sesame Street computer game Elmo Through the Looking-Glass. Oscar the Grouch, Elmo, Telly Monster and a light green Honker with orange hair and a yellow nose sing about that you have to be grouchy to be at Oscar's Grouchy Sundae Party.
