I’m a very stable genius. — Donald Trump

Trump joins such esteemed company as Kanye West in assessing himself a “genius.”  Other people who likely were genii (plural of genius?) such as Einstein, Hendrix, and Steve Jobs don’t say that about themselves, but they probably just forgot.

I think I am, actually humble. I think I’m much more humble than you would understand. — Donald Trump

And of there’s this timeless chestnut:

The difference between stupidity and genius is that genius has its limits. — Albert Einstein
