James Franco gave Bryan Cranston a marijuana painting.
The 38-year-old actor created most of the artwork seen in his character's home in 'Why Him?' and gifted his co-star a "beautiful" picture of a marijuana leaf, but had mixed the drug in with the paint he used.
Discussing the art in the film, he said: "I did a lot of them, yes.
"There was supposed to be a lot of art in the house, and they consulted me, 'What kind of art do you think you would have?' They showed me kind of very generic paintings, so I thought, 'Well, I have some paintings that may be funnier and may be more in line with the character.' "
While Bryan, 60, thought the marijuana leaf painting was "beautiful", his wife Robin Dearden wasn't so impressed.
Appearing on 'Conan' alongside James, he said: "It was a beautiful painting of a marijuana leaf... He actually painted it with real marijuana in the paint...
"I brought it home to my wife. We've been together for almost 30 years, and we have a nice little Connecticut home, and I said, 'Honey, where do you think this would fit?'
"And she said, 'I don't know if it would fit anywhere.' "
But his co-star had a suggestion.
He quipped: "Over the bed."
Also on the show, James showed off one of the pieces of his art, which was called 'Humping Capybaras', depicting two of the rodents - but admitted he had initially made a mistake.
He said: "I got it wrong. I thought they were hamsters, so it was 'F' word hamsters, and then I put it online and everyone was like, 'No, those are capybaras.' So I PG'd it up."
