When Mike decided to do a pin-up of the Punisher with a huge gun against a grafitti-filled wall he was left the the problem of what to use for the graffiti. He decided to fill it using the names of friends. In some cases the friends were "couples." As a joke he listed "Zablo and Sly" because of my admiration for Sylvester Stallone.
If my memory serves me correctly he poster was made about about 15 years ago. [Yep, years before the StalloneZone was created!] Unfortunately some of the folks listed on the poster have passed on. And in many cases the couples have split up.
Last I heard though, Zablo + Sly were still going strong.
