No it's not. The Looney Tunes all exist in other dimensions of our universe; it repeats itself from different perspectives in each galaxy. This means that the characters of South Park, the Simpsons, Futurama,  King of the Hill, and Family Guy, and all the other shows we watch on television exist somewhere else. We just have yet to make physical contact with them. It will be done soon, and all those alternate worlds will be explored, and they will explore ours, and I'll finally see him - Ohh! It will be wonderful, when the day comes! Do you not agree?
