It's dumb filler.. Last time I was really sick I did nothing but try to fall asleep to AS, because I was feeling too weak and shivery to want to get up and throw on a VHS or DVD. There's really not that much else during that time, so it was a bunch of Family Guy, American Dad, oh we know what you want, two more Family Guys! And then half an hour of RC.. usually by that time I was asleep.. inexplicably though, they have Venture Brothers on at like 4AM or some bullshit.. anyway Robot Chicken's sketches are short enough that if it's something really dumb, there might be something kinda funny like this afterwords. Also, they get some pretty amazing actors to voice incredibly juvenile humor.
