Been a few days since the last caption. Time to pick a winner (well, a bit past time... sorry). Looking over the entries, I think I have to go with this one:
"Is he dead?"
"Yes sir."
"Are you sure?"
"Yes."
"I'm not dead!"
"You most certainly are! Don't listen to him sir! He's lying!"
"But I'm not dead!"

Jenni! You (and your caffeine) are up!
