Seth Rogen has taken to Twitter to say he was "legit terrified" that he got Conan O'Brien "too high" after they smoked weed on his show.
After smoking marijuana with the talk show host, Rogen tweeted: "I smoked weed with @ConanOBrien his show and was legit terrified that I got him too high haha. (This was a surreal and shocking moment for me and was genuinely unplanned)."
"You seem like a guy who's relaxed, centered like you know who you are," O'Brien said in the segment. "I'm going to have a lot of free time on my hands now for a while. We're going to start something else up, but I'm going to have some downtime, and honestly - I'm not even kidding - I don't really know what to do with downtime."
"Yes, I get that sense from you," Rogen said before suggesting how O'Brien could spend his time.
"I would suggest - this is going to be hilariously on-brand - try smoking a lot of weed for a long time," he continued.
O'Brien then explained that while he believes weed to be "a fine herb", it's not something that he personally indulges in.
Watch O'Brien take a hit of Rogen's joint below:"I enjoy my lucidity," he quipped.
"Never a sentence I've even thought in my life," Rogen replied, laughing.
O'Brien went on to reveal that when he has tried smoking weed, "nothing really happened", which is what made him wonder about the type of marijuana as Rogen owns a weed company himself, Houseplant.
Rogen then took out a joint.
"I swear to God, this is how lame I am," said O'Brien. "For a second I thought, 'He brought a birthday candle?'"
Rogen explained that for O'Brien to feel the effects of the drug, he was to start off slow with one draw, something he agreed to, before passing it back to him and co-host Andy Richter.
After O'Brien indulged in the marijuana, Rogen said: "I'm so happy with what just happened. I wasn't expecting any of this."
"This is the kind of thing you do when you know it's over for you," O'Brien joked.
Rogen is one of the last guests on TBS Late-Night, which is coming to an end on June 24 after airing since November 2010.
