I had to figure it out; "It's the best," no, that's a lie

from Childish Gambino – Life: the biggest troll [andrew auernheimer] Lyrics on Rap Genius

Meaning

Donald had to figure out (the hard way) that people telling him “it’s the best” may be less than true. These people need to get their brain scanned.

And while it probably isn’t, this could be a reference to Leibniz’s fairly famous (in philosophy) “best of all possible worlds” hypothesis.
