Most Sundays, you'll see a strip or two that are clearly weekday strips, only the cartoonist, on deadline and desperate, has padded the thing out to make a three-panel gag fit a multi-panel Sunday format.
Not in this case. Bud Grace has taken a joke that wouldn't have worked in a three- or four-panel format and not only put it into a Sunday, but then used the maximum number of panels to boot. And there's the appeal of Piranha Club: This is a really stupid joke, and he's not in the least apologetic about it. Not only does he drag it out, but he doesn't even have a final panel where the doctor is sitting in the bar saying something about the encounter. He just uses that last panel to hit us over the head with the hammer one more time.
