Cheesy, rehashed sound effects haunt me

Okay people, I need your help. I'm trying to hunt down 3 VERY SPECIFIC sound effects that get used over and over again in movies and T.V., and I know all of you are familiar with. It started out with a hilarious discussion I had with a buddy of mine, and we can't seem to find them on any online resource sites. If any of you know where I can download them, or a direct link to the file, I would be in your debt forever.
I will describe the 3 different sounds as best as I can, along with an example of where it can be heard, to help alleviate confusion.

# 1. A long, blood-curdling scream of a guy that sounds like he's falling. If you remember the Nickelodean show "AHH! Real Monsters", it played at the very end of the opening sequence when the title popped up. Also it can be heard in most "South Park" episodes when they show Hell. I've also heard it in StarCraft, I believe. (NOTE: This is NOT the infamous Wilheim scream heard in the Star Wars movies, among others. I am familiar with that sound effect.)

# 2. A generic, low-quality sound effect of a group of children shouting "Hooray". It can be heard in almost every single "Peanuts" animated feature when the gang cheers for Charlie Brown or whatever.

# 3. That damnable, annoying baby coo which I have YET to ever hear a real baby make. Sounds like the baby is saying "Ah?..Ahhhhhh!" in a high-pitched warble. Can be heard in %99.999 of commercials dealing with babies, but more specifically in the background of the song "Are You That Somebody?" by Aailiyah.

As bizarre as my obsession with finding these sounds may seem to you, think about the last time an annoying song or soundbite rattled around in your head, causing you to clench teeth and punch things until you were able to find its source. :bnghd: That, or I may have already slipped past the threshold of sanity, so either way, I still look like a lunatic.

Whoever can help me find these, I will dub Thee my personal BTS Savior.

Nevermind. Maybe if I mention John Titor's Ford Pinto time machine or David Icke's Reptilian love child, someone will take me seriously.

hmmm.... i think i know what u mean, now that you pointed those three out

The most infamous "cheesy, rehashed sound effect" has got to be the sound of the dolphin in Flipper.

Every commercial, movie or TV show containing a dolphin has that sound effect.

Peace

You forgot the thunder and lighting sound effect whitch is in every movie up till the 80's
