Incidentally, you can buy the gadget that GilstrapTV and Sons of Arkham use at thesharter.com, lol.
That gadget they used is like a new version of the old "Whoopee Cushions".
(There are at least four places that those kinds of noisemakers should probably never be used: church, the library, a courtroom trial, and a funeral service. Four places they should probably be used would include: at boring pompous city/town council meetings, at rallies like the "pink p---y hats" rally, in Morning Joe's live studio audience, and at DNC rallies.)
