Many scifi stories have entered the public consciousness in subtle ways. How many times have you heard somebody use these phrases in real life and known exactly what was meant?
"Beam me up Scotty!",
"I canna break the laws of physics!",
"Prepare to be assimilated.",
"Open the Pod Bay doors please Hal.",
"I don't think they're gonna to make it.",
"In space, nobody can hear you scream."
"Long long ago in a galaxy far far away.",
"May the Force be with you."
"I am your Father, Luke.",
"Exterminate!",
"I don't think we're in Kansas any more."
"Thunderbirds are Go!",
"F.A.B.",
"Danger, Will Robinson!",
"Anything could happen in the next half hour."
(Ok, the last 4 not so much these days.)
