Seeing double

'Two things. And I call them
Thing One and Thing Two.
These Things will not bite you.
They want to have fun.'
Then, out of the box
Came Thing Two and Thing One!
And they ran to us fast.
They said, 'how do you do?
Would you like to shake hands
With Thing One and Thing Two?'

And Sally and I
Did not know what to do.
So we had to shake hands
With Thing One and Thing Two.

From The Cat in the Hat by Dr Seuss

Just in case anyone's wondering if they were coerced, bribed or cajoled into posing, Tom and Sally (aka Thing 1 and Thing 2) suggested this Blip and they hope you like it!
