Don't act like you don't know how the song goes. "Two all-beef patties, special sauce, lettuce, cheese, pickles, onions, on a sesame seed bun" It's something we've all sung along to at some point.

The Big Mac jingle is synonymous with the famous McDonald's sandwich. But while we all know the tune that lists the ingredients, have you actually had the Big Mac?

Recently, McDonald's corporate offices issued a memo to all of their franchises with an interesting statistic. Only 1 out of 5 Millennials have even tried the Big Mac. This could mean bad news for the burger chain, if they were planning on continuing the success of the sandwich into the future.

While it's not known yet what they will do to change this in the future, Business Insider decided they needed to look into the issue. Check out the video above where they had a group of Millennials try out the Big Mac for the first time. While they seemed to be a bit confused about the need for the third bun, the other views and opinions differed from person to person. Will they be ordering one the next time they see the golden arches up the road?
