This webcomic feels very familiar, but I can't find that I've posted it before, so I'm posting it as though it's new.
Here's part one from Gunshow's cartoon about a lovelorn crab.
You'll have to head to his/her/its website to see part two. I warn you that it's very much worth seeing part two.
Thanks, by the way, to Tastefully Offensive for sharing the comic. Me, I'd rather not be accused of being a freebooter, so I'll send you back to the originator's to get the finale.
