Robin Williams Pocahontas

In the US, for reasons few probably know, we often should Geronimo! when jumping for any significant height. Geronimo was the name of a relatively famous (though for what, I don't know) Native American in the 1800's. Likewise, Pocahontas was a famous Native American woman who served as a guide for the Lewis & Clark expedition to map the American northwest in the early 1800's. The other two words in the meme are actually names of Native American tribes, not individuals, so it breaks down a little there, but there's still a connection.

I think you might be confusing Pocahontas with Sacagawea

Oops. You are correct, sir.
