Take your time and see if you can read each line aloud without a mistake.

The average person can't.

This is this cat

This is is cat

This is how cat

This is to cat

This is keep cat

This is a cat

This is retard cat

This is busy cat

This is for cat

This is forty cat

This is seconds cat

****

Now go back and read the THIRD word in each line from the top down

And I betcha you can't resist passing it on.
