I never saw this special during my childhood, which in retrospect was really too bad. Now that I have a four year old son, I love finding "pre-Elmo" Sesame Street productions for him to watch. This is a fun special - In a nutshell, thanks to Big Bird, the Sesame Street folks find themselves locked overnight in the Metropolitan Museum of Art. At this point, various characters start having their own adventures: Oscar becomes enamored with the museum's collection of ancient Greek statues, believing them to be beautiful "trash" because they are missing limbs, noses, heads, etc.; Bob is forced to thwart Cookie Monster's desire to eat a painting by Paul Cezanne and other works of art; Super Grover tries to make friends with a suit of armor, thinking that it's a real person; and Big Bird along with Mr. Snuffleupagus help a 4006 and one-half year old, cursed Egyptian boy (who presumably lives by day as a mummy in the museum) solve an ancient riddle so that he can transform into a star and live with his parents in the night sky.
