2011.10.20. during Giant Crusher, they were attempting a new pattern where everyone on the team takes their own pick at choosing a block to put down. Jun, who precedes Sho, decided to be a troll and used 25 of the 30 seconds remaining picking his block, leaving Ace with less than 5 seconds. but he was able to choose a block at the very last second and (luckily) Macho-kun stayed standing - cue the dancing chipmunk.
the fact that they are the same person always amuses me. LOL.
