Flash Forward - Season 1 Episode 23 Saboteurs

Every year the eighth graders outsmart Vice Principal Petrowsky and sabotage the float for the Parade of all District Schools and this year Tucker and Christine join in. When Becca wins the Petrowsky's trust by volunteering to be Float Cop, the girls come up with a plan to sabotage the float. At this point, the guys realize it's too late to beat the girls, so instead they join them. They all sneak into the storage room and gather all the toys that the vice principal has ever confiscated from the students and they stuff the float full of them. During the pep rally, the saboteurs shoot them out of the float and into the waiting audience.
