One of the episodes has a "Pop up video" feature. In this mode random little factoids of information pop up on the screen through the episode.
Most of the factoids are like this one:
But when this one popped up I almost fell over laughing:
My excuse for watching what is a very mediocre cartoon, I just finished watching JLU (which is AWESOME by the way), and there are some Superman episodes that add to the JLU story line. While I'm on the topic, watch season 4 of JLU. Seriously, if you at all like super heroes or even think you might, just watch it. Very briefly the idea behind the season is: Can the world trust the JL to protect them, and more specifically can the world trust Superman? What happens if Superman/JL ever goes rouge? Or in short the season asked the question "Who Watches the Watchers?". (Also if you can find it you should watch "A Better world" it's a two parter in the second season, that sets up season 4)
In short, I'm a huge nerd.
