The girls don’t have slingshots, but they do have a regular bar and a talking cactus. Not a comic for youngin’s, but certainly a comic for anyone with a sense of humor, and who doesn’t care about a bit of profanity. There’s a great about page at the website that will probably answer all your questions about it. Go, read, be merry!
The comic updates five days a week, and sometimes more. Start with page 1!
