I wrote a thing in Regular Show #32
I wrote a back-up story in Regular Show #32. It's a fun thing about Pops and punks called "Dandy Drive-in". Christopher Peterson killed it on the art.
It's out now. Get it digitally at ComiXology or find it in print at your local comic place.
ALSO
My story "Tech Giant," which was published last year in Regular Show #20, is included in the Regular Show Volume 5 trade paperback. So you can go get that thing at places like ComiXology and comic shops and book places.
Andrew Stewart did the art on that one and it's great.
