Some great ones in that list. I always look forward to Dilbert. Here are the online archives. Feel free to list your own favorites,

I find it interesting that 9 out of 10 of his favorites are all from two years, and fairly recently at that.
Those close publishing dates makes me wonder how much effort Adams put into searching his archive and picking his top ten. Which of course is how the Dilbert characters react to assignments too. 
Some of his more popular strips have been featured on merchandise. Mouse pads, coffee cups and so on.
The Old Johannsen strip may have been chosen because it was in the right time frame but it was funny.
Man, reading those explanations about why he chose them really drives home how explaining humor completely kills it.
When I was with Volvo we used to swear that Scott Adams worked there.
Something stupid would come down from on high and sure enough there would be a Dilbert strip about a similar thing.
Yeah that’s happened at work a few times. Management comes up with some dumb-ass idea and then, that same week, you see the same thing in a Dilbert strip. It’s creepy.
The one at the top is my favorite.
Are the explanations supposed to be a wry joke?
“this is funny because Wally will pretend to do work instead of doing actual work”
I don’t know if it’s necessarily my ‘favorite’, but this is the one I have on the wall of my cubicle at work.
This one is on my mouse pad. One of my top Dilbert favorites. From 1995
This another favorite because it’s happened to my mom.
NIFTY feature, being able to search Dilbert strips by keywords!
This is my personal favorite, not only because it parodies the invoicing process with biting satiric accuracy, but because my boss once actually did that to me! I brought in an invoice, and she wanted me to shop around for a better price. (It was not a recurring expense!)
I am Old Johannsen, if you substitute retirement for death (I hope - and I haven’t picked out my Wally yet). So that one is certainly right up there on my list of favorites. I do love the Nostradamus one, though.

I once left a job and waited to see how long it would take before my boss would break down and call me to ask what the password was on his computer. He held out six weeks.
This one’s been a favourite for a long time. I’m not even sure why.
There’s several funny ones I remember, but onlyh one that I know the actual date for.
Even though it is several years old, I still think of this one and laugh (especially the new company logo) so I guess that makes it my favorite.
Garfield creator Jim Davis traded on of his originals for Adams’s original of this one. My all time favorite.
This one was always my favorite. Helpfully, it was linked in the Business Insider comments so I didn’t have to do the search myself.
