Why I shouldn't watch Star Trek TNG with my sister

So I'm able to have a few minutes to myself this afternoon and I put on TNG. The episode Disaster was on so I'm happily watching away and then my sister joins me. Now although more of a Star Wars fan she does like Star Trek so I thought no more of it. We get to the point Worf is assisting Keiko deliver her baby and she is now in stitches laughing so hard (OK so it's kinda funny). But then she turns round to me and says I think you're a Klingon in disguise as you want to fight everyone (nearly true,lol).

Sisters!
