We all know that they've had several characters from The Muppet Show and Muppets Tonight on The Simpsons and Family Guy, but they should also have Teen Titans characters on those animated Fox Network comedy cartoon shows as well. We also want them to have references in those shows as well. When do we want them on The Simpsons and Family Guy? 2015! Sign this petition, if you want them to make cameo appearances and references.
