Web Characters

I don't know if any of you have heard of web characters. They're characters that you can make say what you type.
I was recently reminded of them. So I tried to find one online.
Every single link lead me to stuff you have to download or buy. I can't seem to find one where you can make them talk just for fun...no purchase or download required. I have no idea how my uncle found one.
I was excited too. Then, I just started getting frustrated and finally gave up. If anyone knows where I can go to just mess around with one...please tell me. It's driving me insane...
Okay, not literally. I just want to cut loose and maybe have some fun with it. Make fun of co-workers or family members. I could really get a kick out of it.
