So, this is the second part, what happens after the last words...
There might be more interesting epitphs, but I like the short ones best...

- Ludwig Boltzmann (by himself)
"S = k log W"
(The formula for entropy of a system. Boltzmann committed suicide after failing to convince contemporary scientists of the validity of the formula. Grave in the Zentralfriedhof, Vienna.)

- Ian Curtis (Himself, chosen by his wide Deborah Curtis)
"Love Will Tear Us Apart"

- Werner Heisenberg (unknown)
"He lies here, somewhere."
(This is a joke about the famous Heisenberg Uncertainty Principle, which implies that one may not know the position and momentum of a particle simultaneously.)

- John Jones (by Himself)
"Hold my drink, you're gonna' love this."

- Isaac Newton (Alexander Pope)
On his tombstone, "Hic depositum est, quod mortale fuit Isaaci Newtoni," which is translatable as "here is deposited what was mortal of Isaac Newton"
On the adjacent monument "Nature and Nature's laws lay hid in night:
God said, 'Let Newton be!' and all was light."

-Kurt Vonnegut (himself)
"THE ONLY PROOF HE NEEDED FOR THE EXISTENCE OF GOD WAS MUSIC"
