^^ Right! I forgot about that.
This is one of the things I love about SG1 and SGA, we see our heroes' off-duty side with their interests and hobbies and whatever. We also see their personalities beyond their professionalism and their duties. It really helps ground the series and makes the whole setting and situations more accessible and credible because we feel these characters are similar to us.
This and the characters are allowed to let their hair down a bit when off duty...can you see Trek ever mentioning the Simpsons, or Jello Wrestling?
