Mr. Palmero
Mr. Palmero is a chaperone that appeared in The Ugly Truth for the Lock-In and he collected all the kids' electronic gadgets that they had and Greg mentioned that he got mad because somebody would cut the cheese and he couldn't figure out who was doing it. He told the boys if they needed to pass gas, they had to go behind the curtain on the stage to do it. But it turns out a kid who had a head that looked like one of the Simpsons, he made a farting noise from his hands to his mouth. Greg also mentioned that David Rosenberg made it reach its peak when he went down to the music room and brought back a tuba and made a loud sound that said BLARP! He fell asleep when all the boys were awake. He heard the door being knocked by a bunch of angry parents, the ones who let their kids have cell phones, and toke them home around 3:00 because they were trying to call them to see if everything was okay, but since Mr. Palmero toke them, they didn't answer. Mr. Palmero left them with little kid stuff and it was balloons and a ball pit. Greg said earlier on the night he went to brush his teeth at the end of the gym and he heard this weird noise, and complained that his school has problems with rodents but it turned out to be Fregley playing by himself in the ball pit. Fregley didn't appear in the little kid stuff between Greg and Rowley, so obviously the teachers told him to go home because he didn't appear when they were up in the gym or maybe he disappeared and went back home, or he was hiding in there, trying not to get caught.
