Have you ever seen any of these shows (Stargate SG-1,Stargate Atlantis,the movie)?
Yes, all of the above. Atlantis is by far my favorite. The movie's great if you've never seen the show and then it's fun to make fun of. SG-1 is great 'cause I love Daniel.
Which person(s) has had her/his head sucked by an Ancient Headsucker?
O'Neill twice and Daniel once (kinda...if Merlin's memory thing counts)
Here's an easy one : What's Jack O'Neill's favorite TV show?
How many of Sam's beaus have ended up dying? How many haven't (have any)?
Ummm...Narim, Martouf, her ex-boyfriend guy died, so 3 deaths and Orlin, Pete, and O'Neill all lived...so 3 again? There're probably more I don't remember.
How old is Teal'c?
Probably around 200 by now, arguably. 'Cause he was, what, 142 or something in one episode and then aged 50 years in the last episode.
Has Teal'c seen Star Wars? If so, how many times?
Currently,on ANY of the shows,do any of the characters have any LIVING relatives?
Well, Hammond has a granddaughter at least. Sam has a brother who has kids of his own. Ford has his grandparents and cousin. Oh, duh, McKay has his sister Jeanie and her daughter. That's all I remember...and no names for the other people, I'm afraid.
My fave weapon? Probably the rail guns they used on Atlantis. ^_^ Very cool. Also, the flare things. Basically I like all the weapons they used in the first wave night attack in Siege pt. 2.
How many people have the ATA gene?
Well, a lot more than we know, obviously, but Beckett, Sheppard, McKay, Lorne?, either Markham or Stackhouse (no idea which was the pilot in 38 minutes), that annoying Lucius guy, all the ancients we've met. O'Neill maybe?
How big is Atlantis?
Well, McKay compared it to Manhattan in Before I Sleep. I don't know if they've said anything other than that since the first season. Is Manhattan a city? I always thought it was just part of a city. But I'll shut up now. ^_^
Has Sheppard EVER won in a fight against Teyla or Ronon?
He beat Teyla stickfighting in Conversion. I don't think he's ever won in a fight against Ronon, unless you count the time he shot him...but Ronon was still coming after him so probably not. So, Teyla, yes, Ronon, not really.
How many Wraith have been held captive in Atlantis?
Wow, toughy. Bob, Steve, and one or two more? I think two more. Oh, and Michael, of course.
Off the top of my head...I'd probably get more right if I looked but oh well. :D
