"The Daily Show" last night to promote "Minions"-- you can see a clip from the movie in his interview video below -- and the "Mad Men" alum joked that he was going to get in so much trouble with Universal after his conversation with Jon Stewart.

The "Despicable Me" spinoff opens July 10, and Jon Stewart started by saying he hoped the movie was about a quorum of Jewish men and maybe they just misspelled "Minyan." But he said kids really love Minions, including his own kids, joking that they are 18 and 19 and smoke a lot of dope. More seriously, Stewart said not everything can capture his kids' attention like this, and the Jons discussed the universal appeal of the characters for both children and adults.

Jon Hamm: "I think these guys, the Minions, are scientifically designed to be appealing to children. And not only children, but adults. I think the reason they're appealing to adults is they look like capsules, they look like pills. So people are like 'I'm used to that, I'm into it.'"

Jon Stewart: "So you think people are at home going, 'You know what movie I want to see? That Xanax movie.'"

Jon Hamm: "What is it called? Xanax, Xanax, Xanax, Oxycontin? I forget what it's called."

Jon Stewart said he was onto something. He figured they designed and tested the heck out of the Minions to see what the perfect size and shape would be.

Jon Stewart: "In many ways, they did design them like children's crack. Like it is, it's something that just feels..."

That's when Hamm dropped his line about getting in so much trouble with Universal for these jokes.

Jon Stewart: "You know what they're doing right now at Universal, you talking like that?" He leaned forward with his fingers together, villain style. "Yessss."

Jon Hamm: "'Talk to me more about this children's crack.' 'Actually, we'd like to work on that other Minyans movie about the Jews.' 'No, no, no, no, no, let's go with that children's crack story!'"

Haha. They're obviously just joking ... unless everyone comes out of theaters addicted to little round yellow squishy things. Watch more from the Jons here. They really should go on road trips together.
