Cookie Monster

Okay, so I was just looking up stuff to write about for Cookie Monster and I found the wierdest things ever. One website talks about the Origin of Cookie Monster and I had no clue what it was saying. Something about he was made up for some kind of food commercial.. I have no idea but it was kind of wierd. Then I found this other website and it says Cookie Monster's real name is Sid...where do you get Sid from Cookie Monster??? I don't understand that at all. Cookie Monster is just... Cookie Monster. Oh Yeah! And what's up with all the Veggie Monster chiz? Who in the world would change Cookie Monster into a Veggie Monster?!?!?! Like Seriously Dude!!!!!! That's crazy! Cookie Monster is like the best character EVER! That makes no sense to me at all. Arrgggg..... D:<
