Here's more Sesame Street stuff. Tonight we're doing trivia...

Big Bird is written to represent the psychological development of a 6-year-old.

Grover represents the psychological age of a 4-year-old.

Cookie Monster's birthday is November 2. (That's my birthday, too! :))

When Cookie Monster eats cookies on the show, he usually eats fat-free oatmeal cookies or rice cakes painted to look like cookies. Chocolate, oil, and grease can damage a Muppet.

The character of Oscar was inspired by a not-so-nice waiter at a Manhattan restaurant called Oscar's Tavern.

The first celebrity to appear on Sesame Street was James Earl Jones.

While most Muppets have to be replaced every five years, Cookie, Bert, Ernie, Kermit, and Grover are replaced every 10-12 years.

The first episode aired on Nov. 10, 1969.

Bert wears vertical stripes, which make him appear more uptight. Ernie's stripes, on the other hand, are horizontal, making him look more relaxed.

The Count has two girlfriends: Countess Von Backwards and Countess Dahling von Dahling.
