Even the sophisticated mitch4 is confused by this one: “So, what French/English translation oddity, or sound-alike, or pun, would make a plain American sympathy card look to a Frenchman like a thank-you card? I can’t figure it out. Or do I have that set.up wrong? “
Comics I Don't Understand 
Merci / Mercy ?
Or maybe something with “departed”. That could be part of a sympathy message, with a focus on the deceased (or “dearly departed”); while the French visitor, now leaving, can consider himself a departed. But I can’t craft a specific text for the card that would work with this idea.
Soiree / Sorry ?
I’m not sure that a linguistic misunderstanding is required beyond “This is a pretty card” plus making fun of de French guy who can’ read de Hinglish so good. But I’ve asked a friend who is VERY bilingual, native-born American who has lived in France off and on for years. He might have an idea.
The hospitable false cognate jumped out at me immediately (l’hôpital), but the problem with that is that both cognates exist in both languages, (hospital, hospitalier), so it’s unlikely to actually BE used by anyone as a false cognate.
So far, the sorry /soiree false cognate is looking the most promising (Sorry for your loss)…
(“We’re grateful that it was a mercifully short hospital stay, sorry for your loss…”)
Before overthinking this one, recall we’re dealing with a cartoonist who once made a joke on the premise that French “pain” and English “pain” have the same pronunciation.
Has anybody checked out the comments on the syndication site which carries this? I received it in their weekly round-up newsletter.

The only viable suggestion I’m picking up there was from “Egrayjames” and reads “The French word sympathique is used to describe everything and everyone who is ‘nice’; it is not a translation of ‘sympathy’.” So this would mean the visitor saw a card which used the word “sympathy” and not knowing English well he fell for the false cognate and thought it would convey that his hosts had been sympathique.
If this were at “Pearls Before Swine” level of punstry I would try going in the direction of “mercy bouquet” –> “merci beaucoup” but I get nowhere going in that direction.
Friend with lots o’French doesn’t see anything either. I stick by my assertion!
I think the “sympathique”/”sympathy” idea was it.
Yeah, looks like Mitch4 got it. I’m just happy I wasn’t the only one with a problem for a change.
I didn’t really get it, but did pick out a plausible answer from the reader comments on GoComics.
I think that last line “Don’t bother.” may be good advice here. Could it be that the joke is that the “obscure joke” is completely obscure because it makes no sense at all and there really is no way to figure out the logic because there is no logic?
@DrJayKay, I would accept that in some contexts, mainly if I didn’t trust the cartoonist. But I don’t see Gene W intentionally giving us a nothing burger and enjoying thinking about us struggling. (I’m told the reason for so much of that sort of thing on Facebook lately is that the poster then gains “engagement points” which are worth something. But inapplicable here.)
Something similar to your point but differing a little, which I do take as lightly, would be that he realized somewhat too late either that it was a really weak joke/pun, or a too difficult one, and added that “Don’t bother” in the way of apology.
