S: So Mom! I just saw the coolest thing! There are these stickers you can buy to put on your eyelids to make it look like you're paying attention in class when you're really sleeping!
Me: I hate to disappoint you, but the Little Rascals did that back in 1939 and it didn't work for them then either.
S: Wait-- do you actually think my teachers have watched the Little Rascals?
Me: What?! Well no, but I mean that that trick is really, really old. I think your teachers might figure it out pretty quickly.
S: Yes, but technology has advanced a lot since then. These stickers look *totally* realistic...
