Welcome to the Grandpa Sex Machine Archives. Below you will find the various single-panel gag cartoons that make up the entire Grandpa Sex Machine collection. It is unlikely that any new GSM cartoons will be made anytime soon, but if inspiration strikes, he will return. Thanks for the support, and I hope you check out The Moose Riders while you are here. No T&A, but there’s a moose that kills zombies, so that’s kind of cool.
