So about a month ago the idea struck me for a design, simply called "High Fives Throughout History". I started out with no specific people in mind at all, just thought the idea was badass.

So me and my friend started brainstorming hypothetical high-fives that were due, and wrote a big list in my notebook. Although we had about 30 or so ideas, maybe 5 of them were actually good.

The problem is, I can't find my notebook! I have looked everywhere for it, with no luck.

So I ask this favor of you, Threadless community, to help me start bringing this design to fruition again...

Does anybody have some really AWESOME ideas for this design?

All I can remember (out of all of them) so far are:
Ulysses S. Grant OR Frederick Douglas high-fiving Abe Lincoln
Winston Churchill high-fiving Harry Truman
Neil Armstrong high-fiving an Alien
The Wright Brothers high-fiving eachother

Any help for a potentially awesome design?
I'd also like to not make it so centric on America, if possible.
