The setup: I don't remember it too clearly, but I Dilbert is on the run for some reason. Perhaps it was something like he got grandfathered into some benefits as long as no one important talked to him about it
Strip #2: We see Wally's messy office, but today, mercurial fellow that he is, he has decided to poke the bear instead of his usual parasitic antics. Dilbert has camouflaged himself with a vertical belt of many 16oz water bottles, but is wrapped back-bendedly around the back of Wally's CRT as if a martyred saint on a torture device that is both a wheel and the rack. He prays, "Accounting, save me!" (note: Accounting is explicitly demonic in the Dilbertverse)
Strip #3: In a completely dark room, the Pointy Haired Boss is heard wondering aloud to undercover inquisitors that "maybe he's in the darkest corner of the darkest office". Out of exactly that spot, Dilbert mutters, "How did he know?"
