When Mark Wahlberg signed onto Family Guy creator Seth MacFarlane's film Ted, he decided it was about time he watched the Emmy-award-winning comedy series, where nothing, nothing is sacred.
Knowing it was a cartoon, Wahlberg sat down to watch Family Guy with his two oldest kids, who were seven and five years old at the time.
"It was like holy sh*t," he says.
"My wife came running in, screaming at me saying they can't watch this, this is inappropriate, but we were like laughing hysterically.
"It was one of those great moments that you'll never forget with your kids, when you're really both thoroughly enjoying something."
Wahlberg says he had never seen Family Guy or met MacFarlane before joining the cast of Ted.
"I just got a call, we have the same agent, and he'd written the script for a guy from Boston and they asked if I would meet him," he says.
"I read the script and I fell in love with the script and him right away and shortly after that we were off making the movie."
MacFarlane penned the script with longtime Family Guy collaborators Alec Sulkin and Wellesley Wild and he also voices the title character, Ted - a swearing, pot-smoking teddy bear.
In the movies, Ted comes to life as a result of the childhood wish of John Bennett (Wahlberg) and decades later, they are still best buddies.
Their friendship and Ted's slacker lifestyle start to become a problem though, when it comes to John's relationship with long-term girlfriend Lori (Mila Kunis, who voices Meg on Family Guy).
Wahlberg already knew Kunis from their 2008 film Max Payne as well as another co-star Giovanni Ribisi from this year's Contraband.
In Contraband, Wahlberg's character got to beat up Ribisi, but not so in Ted.
"I did get to punch his son in the face," he says, explaining a funny scene from the movie.
"He has an 11-year-old son who is completely obnoxious and my character is not a violent or physical guy at all. He's never hit anybody in his life.
"He's been beaten up quite a few times and this kid is just so obnoxious, that he just hauls off and punches him in the face."
Wahlberg says he likes to alternate between genres like comedy and action and always tries to do the opposite of what his last movie was.
With Ted, he says the script was so well written, "all we could do was screw it up".
"It was one of those special things where you knew you were doing something really interesting and different and cutting edge," he says.
