Visible crew/equipment: During the party, Deb and Hilly join Gary and Wyatt in the bathroom, and when the boys step into the shower enclosure and close the glass door, a crewmember's moving reflection is visible on the shower head.
Weird Science (1985)
1 visible crew/equipment mistake
Directed by: John Hughes
Starring: Bill Paxton, Anthony Michael Hall, Kelly LeBrock, Ilan Mitchell-Smith
Revealing mistake: When Gary and Wyatt come home and see Chet turned into a pile of poo, Chet shoots his tongue from his mouth and catches a fly. Look closely, the tongue flies completely out of his mouth and is attached to a metal spring. (01:24:55)
Wyatt: By the way, why are we wearing bras on our heads?
Gary: It's ceremonial.
[Later, after Wyatt talks to Chet, Wyatt begins to leave the kitchen and Chet sees him wearing women's underwear.]
Chet: Like your panties.
Wyatt: [walking back into kitchen] It's a joke, Chet. Really.
Chet: No. That is not a joke. That is a severe behavioral disorder. Next thing you know you'll be wearing a bra on your head.
Trivia: The town in which Gary and Wyatt live is called Shermer. Another John Hughes reference to The Breakfast Club and Ferris Bueller's Day Off. (00:11:35 - 00:16:50)

Answer: I can't remember Chet's line, but Lisa says "Chip" so slowly and deliberately, it must have been scripted. When I heard it, I chuckled because I thought she was showing him how little he mattered to her by misstating his name.
