The latest promo for the return of Glee is a must-watch for several reasons.

First, it's over two minutes long. Second, it features a few Sue Sylvester quotes that make it clear why this is the funniest character on television. Third, well, we'll need bullet points for these:

• There's the first appearance of Jonathan Groff as Jesse.
• Someone is challenged to a sing-off.
• Three people go on a double date.
• Rachel is seen both donning a Team Finn shirt and telling off her dream man.
• Lady Gaga is referenced, and a Madonna song plays in the background.

The words across the screen near the end: They won the battle... but are they ready for the war? We told you, this is a must-watch...
