After too many volunteers showed up in Hawaii - no need to wonder

- we see here the third round of Judges Elimination, courtesy of Team 3105.
Later rounds switched to steel pipes.
The crowd for their part just loved it, enjoying the syncopated "Chuck Berry" beat: "clack-cla-clack (OW) clack clack (OWW!) clackaclack (OW OWW) clack clack..."
