You can never start them too young.
Ashton Kutcher shared an Instagram photo of his son Dimitri Portwood Kutcher wearing a That '70s Show T-shirt. Kutcher played the character Michael Kelso on the TV hit and his wife Mila Kunis played Kelso's girlfriend Jackie Burkhart.
The shirt featured a picture of Kutcher and Kunis in character along with the phrase "Hello Wisconsin"—a greeting that's yelled during the show's opening theme song and sets the scene for the sitcom.
"Yes, this Is my son's outfit today. #that70sshow #kelsoandjackieforever," Kutcher wrote in the post.
