"It was...yuck. It was really yuck."

Yeah, I'd tend to agree; finding a snake head in your green beans is yuck.  Not sure it tops the classic toe in chewing tobacco, but it's right up there.

(If you're not familiar with the toe case, it contains one of my favorite lines from any case ever: "We can imagine no reason why, with ordinary care, human toes could not be left out of chewing tobacco, and if toes are found in chewing tobacco, it seems to us that somebody has been very careless."  Pillars v. R.J. Reynolds Co., 78 So. 365, 366 (Miss. 1918).)
