(the Internet is Like …)    Eating From a Broken Jar
Be careful when eating peanut butter and shards of glass.
The peanut butter is smooth, nutty and nutritious (unless you are anaphylactic).
The glass is hard, non-nutritious, sharp and it will cut you if you swallow it.

Afterthought:

Oh, and if you’re a rat,

STAY AWAY from free peanut butter,

It will kill you.
