I'm sure everyone remembers this cute gorilla that infects your computer, but did anyone actually install Bonzai Buddy?
For those who don't know, BonziBuddy is a "desktop assistant" who does things like "laugh", "sing", and "schedule". It was created in 1999, and updated until 2005. BonziBuddy was often filled with adware and spyware so he was not a very popular gorilla after awhile.
Here's a video of BonziBuddy, he's very annoying.
