Hamilton mastermind Lin-Manuel Miranda took a second spin on Jimmy Fallon's "Wheel of Freestyle" on The Tonight Show (Oct. 4), serving up impromptu rhymes about Harry Potter and pop tarts. 

Miranda faced off against The Roots' Tariq Trotter, who delivered an impressive rap off the dome, tackling the topics of guacamole, lumberjacks and the Super Bowl.

The victory eventually went to Miranda, though, who spit this memorable non-sequitur in his second freestyle: "I got an erection today, I can't wait to choose my choice on Election Day." He also offered the Hillary Clinton endorsement, "I'm with her." 

Expect Miranda to take both his musical and acting talents to Saturday Night Live when he hosts the Oct. 8 episode.
