The Happy99 worm, also known as Ska or i-Worm, was a worm for Windows, appearing in 1999. The worm would display a gif of exploding fireworks in a window titled “Happy New Year 1999!″. This was the first worm known to spread via e-mail and usenet. Other than attaching itself to the user’s computer, this worm did no damage.
Early 60s Beatles songs are like "I love my girl and she loves me, I'm just a little guy and I'm so happy!" and late 60s Beatles songs are like "Watch Out For The Cellophane Man"
