I was kind of surprised by a comic strip cameo this Sunday. Pig, from Stephen Pastis' Pearls Before Swine made an appearance in Slylock Fox & Comics for Kids. (click on image to enlarge)
Slylock Fox is a kid's activity page with a little minute-mystery puzzle. In this case, there are three cartoon characters. Popeye's necessary, as he's the solution to the puzzle (not to give anything away). Snoopy makes sense, as Schultz's gentle humor appeals and can be understood by both kids and adults.
But Pearls Before Swine? That's a very curious choice. Longtime readers know I admire Pastis' work very much, but I never thought of it as an especially kid-friendly comic. Perhaps Bob Weber, Jr. was thinking of just recognizable figures. Peanuts is published in just about every paper. Maybe Pearl's reached that same level of ubiquity.
Hard to say.
I checked to see if Pig was missing from Pearls that day, but he wasn't. So I'm guessing this was a unilateral move on Weber's part rather than a planned crossover.
No matter, I enjoyed the reference, if not the puzzle solution (which I thought was kind of lame).
