Never really got to. I politely left all of them (when I wasn't having a breakdown), mainly so my employment checks were decent. Although I really REALLY wanted to yell at the boss of my last job "Hey, C----l, is it true that your family sticks their heads in your room at night and ask 'Are you dead yet?!'" (This was one of the places in which I had a breakdown.)

I've written a letter when I quit on bad terms.

No famous parting last words, just wished the son of bitch luck.

The last job I quit I have to admit I didn't feel bad about at all. I was pregnant at the time and my bosses cut my hours waaaay back because they thought me being pregnant would make me unreliable (as in, they were afraid that I may suddenly have to go to the hospital/doctor's office/etc.) Before this, I had been a fantastic worker, loved by my bosses, and could pretty much name my own hours. The cut back in hours was so severe Husband and I didn't know how we were going to survive (this was a time in our lives when money was very scarce). I went to the HR office, and they told me what my bosses did was not very nice, but there was nothing they could do. I was too young at the time to know what they did was very illegal. A few weeks later, an unexpected medical issue came up and I was confined to bed. Before I took to bed, I walked in to work, told them I had been ordered to bed by my doctor, and would not be working for them anymore. As petty as it sounds, and even though I basically proved their point for them, I didn't feel bad about just walking out.
