Yup, the bedside clock strikes 6 a.m. and Phil is as good as new after driving off a cliff and exploding inside a truck. He's devastated to realize his plan didn't work. Now he just wants out. He wants to be dead.
Phil's first order of business is to take the toaster from downstairs, run a nice bath, and get into it with the toaster plugged in. He electrocutes and kills himself, knocking out power to the rest of the building.
Next time we see Phil, he's jumping in front of a truck to kill himself. Then he jumps off the top of a tall building.
Rita and Larry come to the morgue to identify Phil's body. Larry insincerely talks about what a great guy Phil was.
