When Squidward was in the hospital, Dr, Gilligan was his doctor. But when SpongeBob and Patrick were slide whistling, he's in another room sewing a guy closed.
When Squidward was driving, he passes through a burning hoop. But they're underwater.
Patrick puts the old lady from "Have You Seen This Snail?" for being too old. But later, an old lady is seen at the laundry mat and he doesn't arrest her.
Mabel was arrested because Patrick thought she was Manray's lackey.
When SpongeBob was trying to tell Squidward to stop when Squidward was on a truck, and was about to fall from a cliff, you can see SpongeBob & Patrick driving a boat. How could SpongeBob do this if he does not have his driver's license yet? SpongeBob didn't drive, Patrick does when SpongeBob yells to Squidward to stop.
When Squidward was trying to get away from SpongeBob & Patrick, Squidward dived down in Goo Lagoon, as SpongeBob and Patrick did the same. Squidward then paddled until he reached a cave. Although, how could SpongeBob and Patrick apparently know how to swim/paddle if they cannot swim, due do the episode "SpongeGuard on Duty"?
When the man jumps out of the car, he doesn't have a cut or a mark. Why doesn't he have any?
When Squidward yelled, "I never felt so alive!" it's similar like when he said the same thing on the episode "Just One Bite."
It is revealed that Man Ray went to the prom with an old lady named Mabel.
There was a scene of "Slide Whistle Stooges" shown on the promo of SPF5, but it never aired until February.
"My leg!" can be heard in "Shuffleboarding."
Every time someone did something, SpongeBob and Patrick would use their slide whistles to make sound effects.
This is the 18th time the Krusty Krab is destroyed.
In the scene in which SpongeBob first starts talking about slide whistles, he doesn't have any socks on, but they appear in the next scene.
Mermaid Man: Thanks again, boys.
SpongeBob: Just doing our merma-duty.
Patrick: (whispers) And then some.
SpongeBob: (giggling) And then some! That's a good one!
Patrick: For Neptune's sake, SpongeBob! If we are not around pretending to be Mermaid Man and Barnacle Boy, then who is?
Barnacle Boy: Hey, kid, can you give us our Mermarang back? We only got the one.
SpongeBob: Sure thing.
Barnacle Boy: Oh, don't throw... doh!
(SpongeBob throws the Mermarang and it hits Barnacle Boy, who falls to the floor, then the Mermarang goes back to SpongeBob)
SpongeBob: Hey, it came back!
Mermaid Man: Keep on your guard, Barnacle Boy; they're getting ready for another attack!
Barnacle Boy: Those aren't supervillains, it's just that kid, SpongeBob, and his goofy friend.
SpongeBob: I can't believe Mermaid Man hit me with his Mermarang... it's so awesome!
Patrick: Wow, can you beat me up next?
SpongeBob: Are you thinking what I'm thinking?
(Patrick thinks about picking his belly button)
Patrick: Probably not.
Squidward: I DON'T WANNA STOP!
SpongeBob: Are you sure you don't wanna stop?
Squidward: Of course I don't wanna stop, you nitwit!
SpongeBob: UP AHEAD!!!!
Patrick: You never sent me flowers.
SpongeBob: Patrick, go check your mail box.
SpongeBob: Wow, Squidward, you have got quite an ear for music.
Squidward: Don't you... I do?
SpongeBob: Yes, my friend. You have got "the goods".
Female Fish: Someone help! Baby assaulter!
Squidward: Okay, that's enough! You've had your fun!
SpongeBob: True, Squidward, true! We have had our fun!
Squidward: I don't need zest! I need you out of my lampshade!
Squidward: Hey! Get outta here! Huh? (SpongeBob and Patrick laugh) Alright, you two morons! Show yourselves!
Squidward: (sniffs air) Ah, smell that fresh morning sea!
