About this sound

This 10-second clip captures Uncle Grandpa crying during Cartoon Network's CHECK it 3.0 sign-off, with his wavering voice carrying the whole moment. It feels awkwardly sad and oddly funny at once, like a cartoon goodbye that goes on just a beat too long. It comes from the channel's branding era, when the sign-off closed the broadcast day.

How to use this button

End a late-night stream with it after saying goodnight to your viewers.
Close a Cartoon Network nostalgia video right after the final cartoon clip ends.
Send it to a friend who keeps watching cartoons long past bedtime.
Play it at the end of a reaction video when the joke has completely fallen flat.

Where people drop it

TikTok
Post it over a late-night cartoon nostalgia edit that ends with the channel signing off.
YouTube
Use it as the closing sting for a Cartoon Network retrospective or childhood TV video.
Discord
Share it in a cartoon server when everyone agrees it is time to log off.
WhatsApp
Send it to a fellow cartoon fan after a long chat about old shows ends.

Pro tip

Let the whole sign-off play before you cut away, because the joke is how long Uncle Grandpa keeps crying after the goodbye has already landed.

Good to know

Put it at the very end of a nostalgia edit, after the last cartoon moment has finished, then follow it with SpongeBob Sad Song for a slower farewell. For a busier opening, start the same edit with Cartoon Chase Music and let that energy settle before the closing moment arrives.
