* In many episodes, Jeremy complains about piranhas stealing the bait off his line. They're a common source of annoyance for Jeremy. But in the episode "Lair of Giants", a scene shows Jeremy eating cooked piranha meat for dinner. An interesting role reversal, indeed.
** In one of the episodes in question, after a whole day of having his bait constantly stolen by piranha, he hooks something that he says feels bigger than a piranha. When he gets the fish in, it's... a really big piranha. The look on his face says it all.
