Looking at Scott Kurtz’s PVP Online comic from a few days back.
The joke here turns on wordplay, obviously, and also on font choice. (The joke would be given away if Kurtz used a font that allowed for lowercase letter.) But there’s an interesting discrepancy. The lineman specifically uses the phrase “A HIGHER POWER”, which allows us to think for the briefest moment, before we see the lineman, that Cole is having an encounter with the divine. But the company name written on the basket of the cherry-picker is simply “HIGHER POWER ELECTRIC”. If the lineman were introducing himself and his company, wouldn’t he just say “I’m with Higher Power”? So shouldn’t the company name really be presented as “A HIGHER POWER ELECTRIC”?
On the other hand, there is the possibility that the lineman gets a kick out of saying things in such a way. Imagine such a situation in real life. The lineman probably wouldn’t bother to mention the company at all. He’d likely merely say “Look up, son”, or some variation thereof, and leave it at that, trusting Cole’s hearing and sight to locate him. And of course all the visual cues of the work outfit, location, and cherry-picker would immediately tell Cole that he was talking to a lineman. And it probably wouldn’t matter much either.
The joke is repeated in today’s comic, this time by Cole, who has climbed into the cherry-picker basket with the lineman. If the repetition came from the lineman himself, I would take it as a small indication that he enjoys uttering the joke, and so deliberately throws it in wherever he can, even if it’s a little forced. But since it’s Cole who says it, and since both Cole and the lineman react disdainfully when the receptionist takes the words literally, i.e., falls for the trick, it would seem like the discrepancy is not meant to be indicative of the lineman’s character, but is instead maybe a small miscalculation in setup/delivery.
