ELI5: Why can overclocked CPUs execute incorrectly?

When overclocking, there often is a stability test, such as running prime95 and validating the results. So why can CPUs put out incorrect answers?

Think of a CPU like you and a bunch of friends passing sandbags in a long line. When executing normally, everyone is working hard enough and working up a good sweat. You all can keep up just fine.  But when the "boss" says to go faster not everyone can keep up, so some bags get dropped, or are late or get doubled up.  So the whole line gets messed up, not getting the bags to the end in time... A "Wrong" answer.

The same happens in CPUs. Every calculation is a bunch of electrical signals (like the sandbags) being passed along.  When you overclock the CPU the signal timing is to fast and some parts (sandbags) get dropped, or passed wrong, or change when they shouldn't, giving a "WRONG" answer.
