This was cross-posted from a lemmy community (!tails@lemmon.website) that's sort-of bridging lemmy and mastodon. If you're on lemmy.world, they'll already be a post you can visit, to upvote and respond to the original author of the comic, if you wish. If you're not on an instance that's brought !tails@lemmon.website in yet, it can be done so in the usual way, of course.
(edit: just tried this on a different instance. lemmy being lemmy means you might have to refresh a couple of times after clicking the ! link, but that's nothing unusual)
That's really cool! Always thought it was a shame that Lemmy and Mastodon don't communicate more, and that a place like !microblogmemes@lemmy.world is just full of screenshots
Pro tip if you write !tails@lemmon.website without explicitly making it a hyperlink Lemmy will do it for you, and as a bonus the link it makes works on mobile
