- All There in the Manual: According to the book "Coneheads: The Life and Times of Beldar Conehead", "Connie" is short for "Conjaab".
- Awesome Music: Morten Harket's cover of "Can't Take My Eyes Off of You," heard in the final scene and closing credits.
- Hey, It's That Guy!: Yes, that is Ellen DeGeneres as the diving instructor.
Ellen: (Interviewing Lupita Nyong'o) This was your first film! That's amazing! I was in Coneheads. That was my first film.
- Nightmare Fuel: The dentist scene with Beldar's teeth is a little creepy.
- Not So Crazy Anymore: Seedling's suggestion to build an electrical fence along the Mexican border to prevent illegal immigrants from entering the country was utterly ludicrous at the time the movie was made (as shown by his superiors' reactions). Enter the '00s, when that exact same plan (minus the explodey collars) was seriously proposed several times.note
