Sound Over

For my project, I would like to do a sound over project inspired by the DS106 course I took a couple semesters ago. I would first choose a video (preferably an old comedy or cartoon) and use different equipment to replace the sound and basically make my own audio. I am not completely sure which recorder I am going to use, most likely the Tascam, and do not think I would be using a microphone to record since both my hands will be busy making the sounds, so I would use the built in mic in the recorder. After that I match the sounds.
