The McGurk is an interesting illusion that involves both sight and sound. It tricks your brain into hearing the same sound differently based on what you are lip-reading as a person is saying it. For example, a "bah" sound will actually sound like "fah" if you watch the sound come out in synchronization with someone mouthing "fah." In this illusion, what you see overrides what you hear.
