nachtmagazin is the German nightly news broadcast of ARD network's daily news magazine tagesschau.
On November 11, 2009, after the show reported on Sesame Street's 40th Anniversary, with focus on Sesame Street Day in New York City, Ernie made a surprise appearance in the studio.
While talking to host Ingo Zamperoni, he confused the show with another, excused Bert (who was busy sorting his paper clip collection), accepted chocolate-cake on behalf of the show, sang a short rendition of "Quietsche-Entchen," and announced the weather.
