I’ve seen it online in a few places, here on IMDB (https://www.imdb.com/title/tt0094012/trivia)…
The Millennium Falcon from the Star Wars saga makes a cameo appearance in this movie. Given a close look at the exterior shot of the Space Diner, and it can be spotted parked there among the other space vehicles. George Lucas got a chance to read the screenplay before production began, and loved it so much that he decided to have his special effects company, Industrial Light & Magic, help make this movie.
The escape pod launch sequence is an unused clip from Star Wars: Episode IV - A New Hope (1977), provided to Mel Brooks by Lucasfilm.
In a 2013 television interview (shorty before receiving the AFI Lifetime Achievement Award), Mel Brooks stated that he personally obtained George Lucas’ full permission to parody any and all things Star Wars-related but, on one condition, that absolutely no merchandise of any kind be produced from this movie. This is the reason why all Yogurt and the Dinks do is merchandising (it is also why none of the merchandise seen in this movie was ever mass produced or publicly sold in any way).
