Place it at the end of a short edit, after the setup has played out and just before the final reaction shot. Follow it with Goofy Ahh Sounds for a second punchline, or put Fart With Reverb before it when the joke needs a cruder lead-in.
關於此聲音
This is a short cartoon voice clip of about five seconds in which Goofy blurts out a crude, surprised butt joke, stretching the words in a squeaky, overdone style and stressing the final words hard. It feels absurd and awkward rather than angry, and the bluntness catches listeners off guard, making them laugh at how unexpected and over-the-top the line sounds before it ends abruptly.
