Liked the Mr. Pither one you did. I could just see Fry as Mr. Pither! And both Fry and Zoidberg in that situation!
In this one we see Fry and The Professor at a police station
Fry: Good evening, I wish to report a burglury.
Fry: (Speaking up: I wish to report a burglury.
Farnsworth: Speak a little louder.
Fry: (Shouting): I WISH TO REPORT A BURGLURY!!!
Farnsworth: Speak lower.
Fry: (calming down): I wish to report a burglury.
Farnsworth: Nope, still not getting anything. Can you speak in a high
Fry: What do you mean, 'high register'?
Fry: (in a high pitched voice): I WISH TO REPORT A BURGLURY!!
Farnsworth: That's it! A little higher!
Fry: (Still in a high pitched voice): I WISH TO REPORT A BURGLURY!
Farnsworth: A what?
Farnsworth: That's the exact frequency, keep it up!
Zoidberg walks in.
Zoidberg: (In a high pitched voice): Hello, Professor!
Farnsworth: (In a deep monotoned voice): Morning Zoidy!
Fry starts to explain what he's seen in a high pitched voice.
Fry: (still speaking in a high pitched voice): I WAS JUST
COMING OUT OF THE BATHROOM, AND THEN I SAW A BUNCH OF ROBOT GANGSTERS RUNNING OUT OF A BANK WITH $5000 STOLEN!!!!
Farnsworth: I'm afraid I'm going off duty now, talk to Zoidy. (Farnsworth walks
out of the room, and Zoidberg comes to the desk and listens to Fry's
Fry: (Still talking in a high-pitched voice.) I WAS JUST COMING
OUT OF THE BATHROOM, AND......
Zoidberg: (interupts): Excuse me sir, but why the funny voice?
Fry: Oh, I'm sorry I got used to talking like that to the other sergent.
Zoidberg: Speak in a lower register.
Fry: (In a low-deep voice): I wish to report the lost of $5000!
Zoidberg: $5000! That's serious! You better talk to the Detective
Farnsworth walks back in the room, and Bender comes up to Fry.
Bender: (In a deep voice): What seems to be the trouble, Sergent Zoidberg?
Zoidberg: (In a fast voice like an auctioneers): This gentleman here just reported
that he walked out of the bathroom and saw a gang of robot gansters run
out of a bank and said that there was $5000 stolen!
Bender: I see. Where do you live?
Fry: 121 Hollyrow Road on the Corner of 21st street.
Zoidberg repeats the address in a fast voice like an auctioneers.
Farnworth: (In a high pitched voice): He just reported a robbery, Sergent!
Bender talks in an inaduible fast voice about the robbery to Farnworth, who
talks in a high pitched voice which, too in inaudible.
Zoidberg: (Walking up to Farnsworth and Bender, in a loud, squeaky voice): THIS IS
Farnsworth: (In a slow monotoned voice): I must've been somebody else.
Bender: (On the phone): Thank you, Sergent! Don't worry sir, we'll get
this done right away!
Fry just stands there confused.
Farnsworth: (High pitched voice): You think I'm stupid, Sergent!
Zoidberg: (In a fast voice): We should call the SWAT cars!
Bender: (In a slow voice): Good idea.
Bender (On a microphone, singing): CALLING ALL SWAT CARS IN THE AREA!!!!
