Is this missing the last panel, or am I missing the joke?
UPDATE: Checking the Comics Kingdom site this morning, I see that order has been restored (and that last panel). This comic is from May 5: CK now allows you to look forward in time (a week; May 8 is up now).
Comics I Don't Understand 
Do you have a date for that Zits comic? I suspect a panel is missing, because it should be wider than that.
Yes it is very obviously missing the 3rd panel with the punchline. Zits would be a good comic to Garfield Minus Garfield, edit out Jeremy so his parents appear to be talking to themselves.
Was it published on April 1st? Seems like a pretty good Aprils Fools joke.
I agree with Boise Ed and Anonymous. The strip has the wrong proportions to be only these two panels.
Definitely missing a panel, likely with a joke about cramming food into his mouth.
Reminds me of the short lived 1994 animated series on MTV called “The Head” and also the show “Waynehead” and the villain “Brainchild” from “The Tick”. Now that I think about it why were there so many cartoons about characters with comically oversized heads in the mid ‘90s?
Jeremy bears a close resemblance to Petey Otterloop.
Reading your update, I see that the comic in question hasn’t even been published yet (depending, I suppose, on one’s definition of “published”)–at least for those of us who consider Comics Kingdom too poorly-run to contribute to.
The strip to find students with oversized heads and tiny bodies is “Miss Peach” by Mel Lazarus. For some reason the adults in that strip were normally-proportioned, but the children’s heads were four times the size of their bodies.
I haven’t thought about Miss Peach in quite a while.
Jeremy is turning into Beavis.
Ah, now that the strip’s day has arrived, I see that Jeremy’s head is indeed Miss-Peach-sized, presumably due to his cramming for tests.
