That sounds familiar...

On the 4th of July, we watched the DC fireworks on tv. The orchestra played Ode To Joy, and Jenna immediately said "That's from the 9th Symphony!"

Then, this being Sesame Street's 40th birthday, Big Bird came on and started to conduct the orchestra as it played the show's theme song. Jenna said, "Hmmm, that sounds familiar..." (but she couldn't quite place it).
