Former Philadelphia health commissioner Dr. Walter H. Tsou can't help but let out a light-hearted laugh when he talks about flatulence.

But for Tsou, the reason why he and others — including some Democratic delegates who support former candidate Sen. Bernie Sanders — plan to eat beans and pass gas at the Democratic National Convention in Philadelphia is anything but a laughing matter.

"It's a whimsical way of raising a protest," Tsou told NBC News. "There's a lot of things that stink about this whole democratic primary process."
