well, i lived my with not one day without a bad joke so i'll be damned if im not leaving with one (and yes, i aprreciate the irony there), here are some ideas...
"damn, i was one day from retirement!"
"died during a peace treaty with earths closest neighbors, it didnt go well..."
"burried with his collection of gold nuggets and priceless royal jewellery, now dont you go stealing it ok?"
"well that sucked"
or maybe something more mellow like,
"d d d d... dd.. d d dats all folks!"
