There's a scene in Star Trek: Generations in which Data laughs at a joke that was told to him by Geordi LaForge in the first episode seven years earlier. When this is pointed out, Data says, "I know! I just got it! Very funny!"

Flash back to 1987 and the first time watching Spaceballs. Colonels Sandurz says, "Prepare ship for metamorphosis! Ready, Kafka?" I had no idea what that line meant, but the delivery made me laugh.

Flash forward to 1997. I'm working in a bookstore, restocking the paperback classics when I pull out a small stack of, you guessed it, The Metamorphosis by Franz Kafka. I burst out laughing.

Then I almost immediately thought of Data's line and started laughing even harder.

It was a good day.
