Bob Bobberson* the creator of Dilbert has recently put all the comics online. But wait, there's more! For the low, low cost of electrons shooting through tubes at at 88 Mph, you can find the Dilbert comic you want. All of these hilarious panels are searchable. So you can search for PowerPoint comics (like I did) or whatever your silly heart desires. Enjoy.
*That's not his real name. It's something like Adam Scotterson or Scotts McMc. You can look it up with those electrons you're always bragging about.
