The most recent episode of Star Talk radio (pop-science show hosted by Neil DeGrasse Tyson) featured an interview with Whoopi Goldberg, in which she reveals that she has a bit of a science geek in her. One segment of the interview focuses on her involvement with Star Trek, where she reveals a couple of amusing behind-the-scenes facts. She used to unintentionally annoy the sound engineers by making "Swsk" noises under her breath when she walked through a door on set, for instance.
