Me and my brother Jimmy used to make belch tapes when we were kids. We put a lot of effort into them and usually had about 2 minutes of non-stop belching, which we then played back for our mom. When she heard our talents she had tears in her eyes. I like to think they were tears of pride.
If we had had youtube back when we were twelve, you can bet we'd have a clip like this. For all I know, he's a second cousin of mine.
