Don't open that mayonnaise

I bought this jar of condiments so long ago
And now when I wanna use it, I really do not know
Just when did I buy it? When was it made?
A thought comes to me as I twist the lid:

Don't open that mayonnaise
Expiration reads this past May
Don't open that mayonnaise
You might not like what you'll find
Inside

Don't open that mayonnaise
Expiration reads this past May
Don't open that mayonnaise
You might not like what you'll find
Inside

Made of dairy products oh so long ago
Now induces stomach cramping and painful fecal flow
Entering a realm of a pain I've never known
Bowing to the god, the god of porcelain

Don't open that mayonnaise
Expiration reads this past May
Don't open that mayonnaise
You might not like what you'll find
Inside
