Does snacks counts as banana???

“Does snacks count as banana?” Just saw this sentence in Bakatest 2 ep2.
The original sentence is of course  “Does bananas counts as snacks?” But Aki got it wrong since he’s an idiot.
I first heard it in Harvest Moon Friends of Mineral Town. I think it’s a cultural Japanese joke from when kids going on school trips can’t bring more than ~300yen worth of snack, and there’s always one kid asking if banana/fruit counts as snacks. The others kids usually come up with ideas to go around the rule, most of the time one of them makes snacks himself so they were technically free, thus breaking the 300yen limit.
