Quantum Leaps: they're like time-traveling, but less like a DeLorean and more like a really bad idea.
Warning: Quantum Leaping is not recommended. Seriously, don't do it. You will probably get stuck in a never-ending loop of reruns and reboots.
But if you're still determined to Quantum Leap, be sure to set your leap duration correctly. You don't want to get stuck in a quantum leap hold!
