If the secret wasn't out before, it is now.

The most popular pre-game snack in the NBA, the meal that perhaps propelled the Boston Celtics to the 2008 NBA championship, is as simple as they come: Peanut butter and jelly.

In a video which hit YouTube this week, several top NBA players discuss their love for the tasty sandwich. Russell Westbrook, Al Horford and Nikola Vučević swear by peanut butter and jelly, and they'll eat a sandwich (or two) before many of their games.

As you may remember, the originators of this fad were the Boston Celtics. More specifically, Kevin Garnett brought the pre-game sandwich trend to Beantown in 2008. Back then, Paul Pierce would eat a peanut butter and jelly sandwich exactly 55 minutes before every game. Weird? Yes. But it worked.

Now, it's not uncommon for there to be dozens of peanut butter and jelly sandwiches in the Celtics' locker room before games. Buying peanut butter and jelly has even become a ritual for the team's rookies.

Just how much do these guys need their sandwiches before the game? Earlier this year Glen "Big Baby" Davis had a minor panic attack when he couldn't find his.
