Origins of their sexuality

The scooby gang were investigating a ghost known as 'the camera creeper' a villain notorious for filming his victims in sexual situations. Daphne and Velma had gone off to investigate on their own.
they arrive in a spooky looking room with vents all around

Daphne: "jeepers daphne. this place is spooky"
Velma: "dont be silly daphne. you know as well as i do that theres nothing to be afraid of. hes not a real ghost"
Daphne: "i know hes not a ghost velma, but hes still a rapist."
Velma: "Youre over reacting. we dont even know if this ghost is a man. it could be a lesbian."
Daphne: "thats even worse. im straight as a dry pasta noodle. i dont wanna be raped by a woman."

a screen flickers on and a voice can be heard as the room starts to heat up.

Camera creeper: "i suppose its time i get this pasta noodle wet then."
Velma: "Jinkies. the creeper IS a woman."

a thick pink mist starts to fill the room as the heat REALLY cranks up.

Camera Creeper: "This gas makes you super horny... if youre as straight as you say you are daphne. then it shouldnt be a problem... but we both know you arent. OOOOHOHOHOHOHOHOHOHOHOO give us a show girls"

The tv turns off
