. . . you say, and I am happy to oblige as best as I can. 

Arlo and Janis are in their sixties, but you wouldn’t know it from the strip; they were frozen in their mid 40s for a while, and then unfrozen when their kid grew up all of a sudden. The names give them away: Arlo Guthrie, Janis Joplin, and Eugene McCarthy for their kid. The strip was about boomers who grow up and settle down.

None of that is relevant to this, but it explains why the strip suddenly went for a late-60s / early 70s callback. It does not explain what is going on here. The first two panels make no sense to me:

I wish the skink made it to the monkey grass? Janis - bent over with the weight of age and care - says something about lizards, and indeed a skink is a lizard. Did the skink escape yesterday? Are we supposed to remember that there was a skink around in yesterday’s panel? We move on:

So he’s going to pinch her, and his expression suggests lecherous malice. And then this:

Huh? you say. Well. It’s one of those “with apologies to” things comics do when they copy someone else’s style. In this case, it’s “Love Is…”, a saccharine little one-panel about two child-like people defining “love” in a series of simple gestures or actions. It has been running since the reign of Emperor Constantine. The “Kim” thanked at the bottom hasn’t drawn the strip since 1975, and what’s more, she died in 1997. As Wikipedia helpfully explains:

"The main characters are a man and woman depicted unclothed, with no primary or secondary sexual features shown other than depicting only the woman having nipples. It is clear which character is male and which is female due to tertiary features."

Also, here’s news you can use:

"The Turkish version of the strip (Aşk ...dır.) is sold in form of small pieces of comic strips wrapped around gum."

Why Arlo and Janis did this can be explained by the previous strip, wherein the cat is shown attempting to eat the aforementioned skink. "What did we tell you about eating lizards?" Arlo says, with Janis present. She looks away with guilt, and Arlo says "What did I tell you?" Okay. I suppose that explains the panels above, but  “letting her off the hook for not telling the cat to eat lizards” would suggest that a less-loving husband would hold his wife accountable for not instructing the cat to ignore millennia of hard-wired instincts, and that seems a little harsh.
