Visible crew/equipment: When the Overlord is busy destroying the Diner, when he starts destroying stuff on the counter, you can see the small rods pop up that flip the saucers and glasses into the air. You can also see the compressed air they used, to aid with the effect.
Howard the Duck (1986)
Directed by: Willard Huyck
Starring: Tim Robbins, Jeffrey Jones, Lea Thompson, Ed Gale
Other mistake: In the scene where Howard falls asleep in Beverly's apartment window and his wallet falls out, she takes out the money. The city on the bill says Washington DC instead of Marshington DC. (00:19:00)
Continuity mistake: For a few moments during the flight scene near the end of the film Tim Robbins has no handcuffs on, but they are back on again seconds later.
Trivia: When Howard knocks the duck hunter out of his boat, the hunter lets out a "Wilhelm scream."

Answer: As she said to Howard, she believed that he was using his "outlandish" appearance to be unable to find work and collect money through unemployment. She's probably dealt with people who did the same thing and was eventually sick of it.
