One easy way to test your memory: Watch any TV show or movie that has a stacked cast.

Normally at some point along the way you’ll spot an actor you know from something else. You can’t recall the actor’s name, but also can’t place what you’ve seen them in before.

Next thing you know, the show is on pause while you desperately crank up the Google info finder to solve this new mystery.

When you finally track down the answer, it often is annoying in an “I should have known that” kind of way, thus often dissatisfying.
