Dee Dee Be Deep is the first segment of the seventeenth episode in season 2 of Dexter's Laboratory. It originally aired on November 5, 1997.

In this episode, Dee Dee is trying out for the Singing Minors Choir, but her off-key singing voice drives Dexter crazy. He then alters Dee Dee's vocal cords to make her sing beautifully, but her meddling prior to this makes her voice more baritone than usual.


Dexter is in his lab working on his latest invention, but just as he prepares to put in the final screw, he is cut off by Dee Dee singing the song "On Top of Old Smokey" off-key. He storms out of his lab and goes to Dee Dee's room. After opening the door, Dexter is greeted by a gust of wind coming out of Dee Dee's room. After managing to get in, Dexter requests her to stop singing, but she refuses to do so, then Dee Dee explains her reason for her singing: There are tryouts going on at her school and she's practicing to make sure she's ready.

Back in Dexter's lab, he invents a piece of bubblegum intended to mute Dee Dee's singing as she sings the song "Old Folks at Home". Once Dexter sets his coordinates, he fires the bubblegum into Dee Dee's room and it lands directly in her mouth. To see his invention in action, Dexter goes to Dee Dee's room and finds her blowing a bubble, which then flies toward Dexter and traps him inside.

Sometime later, Dexter comes up with an idea of changing Dee Dee's tone to make it more harmonic. Inside the lab, Dexter explains how his latest invention will make Dee Dee's voice better than the one she currently has. Before she steps inside the machine, Dee Dee sets the tone from treble to bass. After stepping inside, Dexter lowers a glass dome onto Dee Dee's head and she starts to sing as he plays a few notes.

Thinking it was a success, Dexter's epiphany quickly turns sour as Dee Dee's voice goes from angelic to baritone. In addition, whenever Dee Dee talks, everything around her starts to shake. With her new voice, Dee Dee heads to the singing tryouts, ignoring Dexter's plea for her to come back. At singing tryouts, Dee Dee starts to sing once more, but her voice destroys everything around her, including the school auditorium. The teacher, shocked to see the auditorium in a rubble, faints. Later, Dee Dee is in a park crying over how her new voice sounds "dumb". It attracts the attention of three barbershop singers, who let her join them.

At Dexter's lab, he is again finalizing his invention, but gets cut off as Dee Dee and the barbershop singers all sing "When the Saints Go Marching In".
