'Harold And Kumar' Star Tom Lennon Explains How You Get Toddlers High

If you're heading out to see "A Very Harold And Kumar Christmas" this weekend, you can expect to be highly entertained by its stars, John Cho, Kal Penn and, of course, Neil Patrick Harris. You should also keep an eye out for the scene-stealing supporting players like Jake Johnson and Tom Lennon.

MTV News was lucky enough to catch up with Lennon recently during the film's press day and in addition to being consistently hilarious, he was very helpful in explaining one of the film's big mysteries: how they managed to get the 2-year-old actresses in the film to appear as though they are high as a kite.

“There was a baby whisperer on set, which was the only way we really did anything because when I first read the script I was like, ‘Oh [my character] has a baby with him the whole time,’ and I thought, 'Oh that’s great, babies are super easy,'" said Lennon. "I’ve had a baby, they don’t do anything. Well, they cry once in a while but then they mostly kind of sleep and go, ‘Waaaaa’ and look at you."

"Two-and-a-half-year-olds are perfect killing machines," Lennon said seriously. "They hate everything, and that’s what we cast in this movie, so we had at all times on set three 2-and-a-half-year-old babies who were various levels of pissed off every second. People were like, ‘Do you feel bad for the baby, the baby had to do all these crazy things in the film?’ No, I feel bad for the adults who were there. It was intense."

Lennon went on to say that their only savior on set was the film's "baby wrangler."

"There is stuff those little girls do in this movie that just blows your mind. Just all the cocaine stuff and the 'I want it, I want it, I want it.' There was a game that they were taught to create all this, they didn’t say to the baby, 'Hey, you’re on coke and rub your gums,’ no, there are fun like 'We're brushing our teeth' games," he explained. "There’s a game for everything to make it work. It was surprisingly good-natured. The girls actually a had remarkably nice time and their trailer was pretty big. Almost as big as mine.”
