obama soundboard

How do I capture audio from different soundboards to make a pretend conversation?
Like the guy who took a Cookie Monster Soundboard and a Barrack Obama soundboard and made an audio file that sounded like they were having a conversation with one another.?
If you can’t extract the sounds from the sound board, you can capture them by playing the sounds on one computer, and using a second computer to record. You use a wire from the first computer’s speaker output jack to the second computer’s mic input jack. Then, when you have all the sounds saved separately,arrange them in a sound mixer program so they sound like a conversation.
