The Wizard of DoS

They're 3 bad souls. Oh me, oh my.
They'll steal you stuff, they're none too shy.
But never mind those three,
We're protected as you can see,
Just as long as you click safely,
In this scary land called the World Wide Web.

Oh the World Wide Web is a very scary place,
Where everyone wears a very scary face,
And the sites get pwned with ads,
And no one catches the cads.
In that scary land lives the Wizard of DoS

 this was inspired by a tweet by josh corman quoting anthony bourdain. and if you haven't figured it out, it's a lyrical parody of the theme song from the wizard of oz cartoon
