If your parachute doesn't work, don't worry.
You have the rest of your life to figure it out.
Okay, so listen up, buttercup. The joke is, like, when your parachute fails, you're obviously gonna die, right? But this joke says you have the "rest of your life" to figure it out. Get it? 'Cause you're falling to your death! Ha! You probably can't even change a lightbulb, huh?
