Right you are! Well, then, I suggest an improvement on my suggestion above.
Instead of having the balloons merely inflate and float to the ceiling, don't close off the fill-neck. Just let them loose so that they rise a little and then race around randomly deflating and making "fart" noises. Hilarity ensues.
I'm undecided whether that scenario is best done all at once, or sequentially, to extend the duration of the noise.... Opinions welcome.....
Should do a “Roger Waters” and have an inflatable pig floating around during the speech.
I might even be persuaded to watch with that scenario you described. 😂
