Everyone knows that smoking weed with Snoop Dogg is horribly detrimental to one’s sobriety.

Just ask Matthew McConaughey, who got so high off the rapper’s weed one time that he rapped for more than half a day … or at least that’s what Snoop says.

Snoop and Matt appeared on Jimmy Kimmel Live! last Wednesday (Mar. 27) to talk about their upcoming film, “The Beach Bum.”

Towards the end of their interview, McConaughey told a hilarious story about filming his first scene with Snoop. Before shooting the scene, Matt says Snoop switched the actor’s prop weed for the real thing and the results are absolutely hilarious.

“I didn’t say another word of English, really, the rest of the night,” McConaughey told Kimmel. He then turned to Snoop and added: “You said I rapped a lot.”

Snoop replied, laughing: “You rapped for 13 hours straight.”

Snoop Dogg and Matthew McConaughey is the duo we never knew we needed until now.
