I'm not sure if it's already been broadcasted already or not, but this seems like a pretty neat crossover.
Found it and watched it on YouTube myself. It was pretty great for what it is; just 10 minutes straight of Sonic references. Most of them are to the old cartoon though what with this being a TV thing and all.
