From the Anti-Barney Humor Wikipedia article:
The Barney Fun Page is an early website that allows users to attack a crude drawing of Barney with icons representing a knife, gun, and other weapons. Hosted originally on a University of Alberta computer system, the website was created in 1994. It is among the oldest websites in the world still operating as of 2025.
I hate you
You hate me
Lets chase barney up a tree
With a big fat shotgun
Shot him in the head
Now we’re glad barney is dead.
Our version was slightly different at the end:
With a big fat gun
And a bullet in his head
Aren’t you glad that fuckers dead
