Last night I saw an episode of the TV show Stargate SG-1 in which Colonel O'Neill (Richard Dean Anderson) is introduced to a Major Newman, and uses the traditional Seinfeld inflection as he says "Hellooo.... Newman!" Yet another example of how Seinfeld has become a part of our culture!
Though this was the first time this episode was seen in syndication, it was originally aired on Showtime a year or two ago. I wasn't sure if it was already discussed back then, but I thought I'd mention it just in case.
