Mama Cass: I always thought that Cass Elliot of The Mamas and The Papas died in the middle of eating a ham sandwich and drinking a Coke while lying down -- because that's the urban myth, probably because that's what Dr. Anthony Greenburgh publicly declared after being the first to examine the big Mama. But it turns out that Greenburgh was way wrong, and Elliot actually died of heart failure at the ripe young age of 32. However, there was an uneaten ham sandwich at the death scene, so you can see how the doctor could have jumped to that conclusion. The fact that the rumor persists to this day is really what makes the ham sandwich all the more amazing.
