I love panel four, seeing Wally in action through his inaction. You wouldn't think being aggressively unhelpful is possible, but in that one panel Wally manages to pull it off.
"Since how long has asok been an intern? Maybe he doesn't get any performance appraisals."
This happens all the time at my company. We hire an intern, milk all the work and "smarts" we can out of them, never promote them, and then when they leave we are screwed because nobody can do their job!
