This came up at work a few days ago: how many different ways can a person be killed that involve a banana (or bananas) as a crucial component?
For example:

Slip on a banana peel and crack your head.

Choke while attempting to eat too much banana.

Crushed to death under huge pile of bananas.

Smothered by being wrapped in a blanket made of stitched-together banana skins.

Stabbed to death with a (very) frozen, sharpened banana.

Hanged or garroted with a rope made from the fibers from a banana peel.

Drown in pureed banana.
And some less direct ones:

Suffer from such severe bananaphobia as to have a fatal heart attack at the sight of one.

Become convinced you are a banana, leap into a swimming pool attempting to make fruit salad, and drown.

Be sexually obsessed with bananas, be caught in an act of public banana-related perversion, and die of embarrassment.

Variant - choke while attempting to fellate a banana.

Be beaten to death by an angry gorilla from whom you are trying to steal a banana.
I am sure there are more, so let your twisted imaginations run free!
