Try The McGurk Effect - Is Seeing Believing? (hunch.com)

In the video we see a man saying 'baaa, baaa, baaa', but when he makes an 'f' shape with his mouth when he says 'baaa', we actually hear 'faaa'. It is an illusion.

Anyone know other examples of senses messing with each other?

This was on reddit the other day direct with a link to youtube, this feels like blogspam to me cashing in on hunch adds no value and shows a tiny player.
