Sunday is Monkey Covers day here at YACB. Because there's nothing better than a comic with a monkey on the cover!
I've heard of maving a monkey on your back, but being on the back of a monkey is a whole different story on Andi Watson's cover to Skeleton Key #22 (1997).
(Standard disclaimer about giant gorillas not really being monkeys applies.)
