I'm not really a fan of comic strips (other than classic Peanuts), but this has to be good for dads, right? I found an article this morning saying that a comic strip about a single dad and his daughter called "The Humble Stumble" has been picked up for syndication in some newspapers around the country. Previously it's just been available on Comics.com.
Check out The Humble Stumble (I particularly like this one) on comics.com.
