It's called "The Imaginary Man". It's basically the first beepbox song i posted that had lyrics. Lyrics Verse 1 Standing in at 10 feet tall. You may think he's real, but not at all! Well, look at me. Here's a fact to lend; His name is Wilt and he's an imaginary friend! Verse 2 Lives in Foster's and is entirely red. He has a stub and sleeps under the bed. The left side of him has a googly eye. He's a pro at basketball and he likes to see you try. Verse 3 Gigantic number one slapped on his chest. You know, he's way nicer than all the rest. Apologetic, kind, and he's cool! Never heard of him? You might be a fool.
It's so obvious when I say... Cartoon Network.
