If you somehow don't have digital copies or DVDs to whatever other media so that you can watch it whenever you want, Adult Swim will be airing the first season of The Venture Bros.
starting in January! The only catch it is will be airing Sunday mornings at 5am (eastern)... which is also Saturday night depending on how late you stay up. Either way, it's a great way to watch the show in its natural environment; live on a television with commercials and everything! Weird!
The whole thing kicks off with "Dia de los Dangerous!"
which airs at 5am on January 6th (the night of January 5th, if you're inclined). You can also catch replays of the end of season seven at the much more reasonable time of 12:30am on Sunday nights, though I'm not sure if they'll air the entire series in that far more coveted time slot just yet.
