So I just did a Google search of (without quotes, too): turtle female lactose intolerant obsessive flosser.This strip was the first result. That’s awesome.
Since nobody has named them all yet, they are (from left to right): Robotman and Monty (from the strip on here called “Monty”—a good strip, IMO), Captain Haddack from Tintin comics/books, Dilbert from “Dilbert”, Bucky, Rob, Satchel, Steve Dallas from “Bloom County/Outland/Opus”, and Calvin and Hobbes from “Calvin and Hobbes”.
Arlo and Jan (one of my favorites)
