One of the best phrases in the English language is "It's showtime, baby." This can mean any number of things. It can mean that Dad is letting us know that the brats are about to go on the grill. It can mean that the guests are here for dinner and it's time to pretend you weren't just having a loud argument with your family. It can be used when walking into the office on a day when you have to present in front of your boss. And finally, it can be used when you're backstage and the curtains are about to go up. Honestly, it's probably the least common use case out of my examples.
Anything can be a show, all it takes is a little razzle-dazzle. Memes can be a show, just wait and see. These memes have buffed their shoes and slathered on the grease paint, and they're ready to take center stage.
