Simon was late coming to the stage, and Sen. Al Franken and comedienne Sarah Silverman were asked to stretch out their act, which was not going as well as planned.

Franken told the delegates that he was a Hillary Clinton supporter and Silverman countered that she was a supporter of Sen. Bernie Sanders.

“And this past year, I’ve been feeling the Bern,” said Silverman to cheers from the Sanders supporters.

All the courtesy Sanders supporters gave to Silverman went away and the chants rose up: “Bernie! Bernie! Bernie!”.

As Franken tried to speak, the enraged Sanders supporters drowned him out: “Bernie! Bernie! Bernie!”.

The Sanders supporters were standing and shaking the “Stronger with Unity” signs convention organizers had passed out, but Sanders supporters had copyedited with markers to read: “Stronger with Bernie.”
