Trivia

 * Penny has a chance to restart her acting career with an offer to be in the movie "Clerks 3".
 * Penny uses Sheldon's knock like she did when she was furious at him for taking her clothes in "The Panty Piñata Polarization".
 * Extraterrestial alien life does exist in The Big Bang Theory universe -- at least if the final scene of this episode can be considered canon.
 * The alien spaceship in the final scene somewhat resembles the human-built BC-304 class battlecruisers from the science fiction franchise Stargate. Both ships have side hangars opening to the front (assuming the openings are hangars on the alien ship in this episode), the shape of the prow is fairly similar, and both ships make a similar "engine" noise (disregarding the scientific implausibility of sound in a vacuum) -- a deep, pulsing hum.
 * Goof: Leonard says that aliens had to figure out how to build a record player to listen the gold record mounted to the Voyager space probe; however, a diagram on how to build one was included on the spacecraft.
 * Second episode where the softness of Leonard's skin was compared to veal.
