I understood the shirt the moment I saw it!

When I was young there was something (not sure if it was a shirt, might have been a poster?) which had the words "PLAN AHEAD" on it, and the last two letters were much smaller than the first because they had run out of room. :)

I see the:

PLANNIN
              G

As exactly the same. :)

Thanks for this Jerry; although I won't be going into the t-shirt selling business any time soon, those ten items apply to a great deal of other endeavors as well. Take care!
