Hi. Apart from the obvious, is there anything odd about the way I look?
Now we're not going to change anything
apart from which way up I am.
As I turn the right way up...
...maybe things aren't quite what they seem.
Now what we actually did was took my mouth
and turned it upside down.
And the same with my eyes.
I may look a bit odd like this
but quite normal when turned upside down.
Strange, hey?
