Oh. Whoops.
But you see, Rickroll has a hard life. It's practically the only video anyone expects to watch anymore. Your grandmother sends you a link, and you're instantly skeptical. Nice try, but I know that's more than just cute cats. Its existence is now feared and predicted - you can never win; you can never surrender. You can never give it up.
So share this; for Rick's sake. We titled the post for you so your friends will have one last chance at being surprised, but you already know what's going to happen. They're no strangers to Rick.
