Funny / Shriek If You Know What I Did Last Friday the 13th

• Apparently, a frying pan makes a "Motherfucker" sound when hitting someone.
  • On that note, the Killer being startled when a bat comes flying through the window and hits Principal Interest.
• The "Greased Frightening" Song: "I want my mommy, oh I want my mommy..."
  • "Of course it sounds stupid if no one else sings."
• "Wrong Way, you idiots. The door's downstairs."
  • "In some aboriginal tribes, men wear dresses as a sign of power."
  • The Killer breaking the 4th wall by stabbing one of the pop-ups after it offends him.
  • The entire Chop-Up Video sequence, for that matter.
• The Sex Ed teacher's commentary on the tacky wallpaper in the educational film he shows the class, preceded by his demonstration on what sex is... with sock puppets.
  • Then there's his Lack of Empathy to a girl going into labor during class, and smugly asking her if it can wait until prom.
• "...and that's how I knew I wasn't a lesbian."
• Barb beating up the Killer in the girls bathroom in a parody of a Mentos commercial, all while being witnessed by an old woman who gives an approving nod.
• The Killer attempts to kill someone in the girls shower room by stabbing through a peep hole where they were looking. Que the janitor walking in and seeing the killer (who's naked except for his mask) from behind, and looking like he's masturbating.
• "24 hour pizza. If we're not here in 24 hours, we're not coming."
• The killer's constant failures to actually kill anyone.
  • Well, anyone who's not a background character.
• During the Christine sequence you can actually hear the killer backing up every time the camera switches to Slab.
  • The Killer getting pulled over by a traffic cop before he can run down Slab. Keep in mind, that this is taking place inside a school garage.
• By the time we get back from Martina's flashback of her Dark Secret, Mrs. Tingle's asking the class if Frankenstein was circumcised. And totally oblivious to the multitude of guns aimed at her by the rest of the class, and the Killer tying a noose around her neck.
• The Killer shows up to kill Martina while she's running track. As he tries to catch up to her, the crowd starts cheering for him which makes him lose sight of his mission. He then focuses on finishing the race before her, which he ends up doing. As he's being carried away by fans, he looks back realizing his mistake.
• When Barbara tries to escape the killer by going through the cat flap, she gets stuck much like Tatum and Tina did and it seems like she might meet a similar fate when the killer eyes the switch to the garage door. However, the switch he hits is just a doorbell, so he tries another one and it activates a disco ball. The third one he tries is the actual switch, but he runs into more bad luck when an officer's radio ends up interfering with the signal, causing the door to keep going down when he keeps trying to raise it.
• Boner saying that roofies aren't getting him laid and Slab responding by suggesting that he's not taking enough.
