I was thinking about this. The acoustics are probably designed so that the people on stage project the best so it would make sense for these people to turn their backs on Hillary and yell “Lock her UP” while farting. I don’t have the skill of farting on command so not sure how they are going to do it but there are apps for that. Seriously, a colleague and I had a fart off at work a few years ago. I won because my app allowed me to record a fart. (My granddaughter and I did the classic blowing into the elbow thing).
Simethicone or strong mint tea enable anyone to time these things!
