the Golden Age of Adult Swim was when it aired Space Ghost, Sea Lab, Aqua Teen Hunger Force, Home Movies, and I am not sure what others shows but it was around that time.
Then Adult Swim went through some changes and lost Space Ghost but still had some good shows. Mostly Reruns I guess.
Now there aren't too many shows on Adult Swim I care for. I don't watch alot of it but I do like the Tim and Eric Awesome Show, I watch from time to time Robot Chicken, and Aqua Teen Hunger Force. and Venture Brothers is good.
I watch ATHF reruns, and Futuramma Reruns too, and sometimes Family Guy.
