Carl Fink submitted this Hägar the Horrible strip, commenting: “I think this is way too obvious to actually be an Arlo. Is there a category for ‘The Funnies just showed a young couple having sex in front of their neighbors, only slightly off panel’?“
There are a series of fine distinctions related to CIDU Bill’s “Arlo” designation. Carl is absolutely correct in recognizing that this comic does not qualify for an “Arlo Award“, because there isn’t any hidden wordplay, and nothing has been secretly smuggled past the syndicate’s censors; the hot action is right there (to the left of the second panel), for all of us (not) to see.
Whether or not this is “Arlo material” is a matter of subjective opinion. There is nothing objectively offensive about two pairs of underwear, and especially not with such frumpy ones as shown here. I don’t think that even Bill would have thrown this comic into his “Arlo Page” purgatory, and he was especially careful about not wanting to offend even the most sensitive of CIDU readers.
Nevertheless, this example is surprisingly risqué for a syndicated comic, and all the more so for one published by King Features, which in my experience has always been the most “sanitized” of all the syndicates. It also shows that someone else (presumably Gary Hallgren, for lack of any official information) has taken over the writing duties for “Hägar”. I cannot imagine that Dik or Chris Browne would ever have produced a comic like this one (even if their name still appears on it).
If this strip (pun intended) didn’t trigger the KF-censors, then it’s probably because the editor decided that the “sex” is indefinite and unprovable: concerned parents could theoretically explain to their curious kids that the new couple have just changed into their pajamas (to go to Hägar’s bed). The duplicity is psychotic, but that’s the way Americans behave about this subject: remember the “wardrobe malfunction“?
Comics I Don't Understand 
It’s a CIDU in the sense that we don’t understand why this sort of thing is appearing in Hagar now. Probably due to the inevitable shift in tone as a new writer takes over.
I hope the next step in evolution isn’t talking pets.
The geometry of house Hagar has always been a bit odd. It seems to be one room, with cooking in a fireplace. As needed, however, it adds a kitchen with sink & running water, multiple bedrooms, and possible an internet connection.
Downpuppy (2): Sometimes, as on July 28, it has multiple rooms. The exterior varies among straw, stucco, and clapboard. The house also seems to be mostly isolated, but sometimes with fairly close neighbors.
This being in the Mort Walker – Dik Browne lineage, are you sure they aren’t just having a fight like Beetle and Sarge, and just off panel is a big cloud of dust with a bare foot or two sticking out and clothes flying all over the place as we can see?
What was duplicitous about the wardrobe malfunction?
@ Powers (5) – OK, I admit that I could have worded that better. The duplicity part was intended just for those parents; the general American attitude toward uncovered skin is psychotic.
