I recently did a song that was political at a festival. It was titled "I'll Tell You the Good Things Our Government's Done, with apologies to Tom Paxton." I told the audience I'd been working on the song since 1978. A small untruth which I'm sure will be overlooked by history.

It went like this with two other voices harmonizing on the word 'done'.

Deep breath and "I'll tell you the good things our government's done."
Expel remaining air, look around the audience, step back and wait. It took about five seconds of silence and the laughter started. It lasted substantially longer than the song.
