risible (adj.) - eliciting laughter; ludicrous.

Lights up on a stage with a podium. A serious young man enters with a stack of note cards which he places on the podium. He clears his throat.

YOUNG MAN

[in a serious, no-nonsense tone]

Tonight I would like to talk to you about a serious subject.

Muffled laughter is heard from the audience. The Young Man looks a little surprised, flustered, but he continues.

YOUNG MAN

An issue...

A little more laughter. He tries to ignore it.

YOUNG MAN

A serious issue...

Even more laughter. Again...

YOUNG MAN

A very serious issue that threatens the lives and livelihoods of each and every one of us...

More laughter - almost screaming.

YOUNG MAN

And that of our children...

Laughter!

YOUNG MAN

[attempting to speak over it] And our children's children...

More laughter - cacophonous!

YOUNG MAN

[shouting now - over the din] And we must come together, in a bipartisan manner [the laughter is almost unbearable] if we are to save...this...great...nation!

The audience is howling, even throwing objects, hats, confetti, vegetables, flowers! The young man gathers up his note cards, and knocking over the podium (or almost) stumbles out. The laughter continues to a fevered pitch and then blacks out.
