I guess we'll find out her limit....

Considering her eyes are already swirling and she's at her 15th now, I don't think she'll be able to eat more than 20, and even that's probably above her limit.

And even if she was able to eat lots more, competing against Hungry nun in how much she can eat? She might as well rise white flag before she even tries.

Don't underestimate gorillas, they can go far over 15 bananas (although in the wild they don't normally get to eat bananas at all).

Congratulations, you've doubled your daily exposure of radiation. Literally, you are exposed to 100 bananas worth of radiation daily.
