Zac Efron in 'Neighbors 2: Sorority Rising.' (Universal)

Zac Efron talks truth in ‘Neighbors 2’ — ‘I suck at math. I’m good at weed.’

It's a universal truth: Complex mathematical equations become more managable in the context of illicit drug transactions

If you liked the Seth Rogen-Zac Efron stoner comedy “Neighbors” — I’m more of a “This is the End” man, myself — then you surely know that “Neighbors 2: Sorority Rising” hits theaters on May 20.

For those living under a rock, that’s one month from today — 4/20, natch — so we wanted to share this 420-friendly clip from the forthcoming sequel where Efron’s character Teddy speaks a universal truth about complex mathematical equations becoming more managable in the context of illicit drug transactions.

“They have seven pounds of weed,” Teddy says effortlessly. “They can sell it for $50 a gram if they want to. If they move it all, that’s over $112,000.”

To which Mac (played by Rogen) quips: “You’re incredible at math.”

Teddy responds: “No, I suck at math. I’m good at weed.”
