I feel it is immensely important that you, the reader, know that in this volume of the Ghostbusters comic series, there is an extended scene in which Ray Stantz dreams vividly that he is Austin Millbarge (Dan Aykroyd's character from Spies Like Us) snowboarding in the USSR with a busty blonde woman clinging onto him being chased by two masked pursuers who double as a covert Blues Brothers reference, at which point the busty blonde woman partially transforms into a blonde, blue-skinned, large-breasted John Belushi (as Jake Blues aka Ray's spirit guide) who then proceeds to pester him regarding the issue of Dimensional Shifting.

If that doesn't convince you to sit your ass down and read this comic series, I just don't know what will. You can't get this shit from anywhere else.

Also, there is a very obscure, blink-and-you'll-miss-it reference to Dan Aykroyd's niche 1990 comedy Loose Cannons. And I suspect I and the illustrator are the only ones who got it.
