How the SpongeBob Voice Was Created (04:04–07:28)
- Creating a voice for an inanimate object was “very freeing” for Kenny as there was “no template.”
- He chose a “childlike, non-age-specific, enthusiastic and just kind of weird” voice, eventually described as “elfish,” “helium,” and “maybe childish.”

“I have a tendency to retain water. Terry, this is SpongeBob on a very… I’m feeling very obese and very large today.” (07:34) - As “Child” SpongeBob:
“This is SpongeBob as a child. I am in Sponge kindergarten. Ay, ay, ay, ay.” (07:46) - As “Deviated septum” SpongeBob:

Finding His Comedic Voice and Standup Roots (21:23–24:03)
- Kenny was shy as a child—voice acting allowed him to be both “a little bit shy and also an annoying, irritating show off at the same time.”
- Stand-up was “very kinetic, pop culture-oriented,” and naturally transitioned into sketch and voice work.
The Decline of Impressions in Comedy (24:03–26:13)
- Growing up, comics based acts on impressions of old stars and politicians; by Kenny’s era, impressions felt “square.”
- “My strength was always creating characters out of whole cloth...my cartoon voices have been the result of my highly unsuccessful and lame attempts at impressions.”
