As the saying goes, father knows best, but unfortunately not in every case. A Polish father has been questioned by police in Warsaw for allegedly giving his young sons lessons on how to drink and smoke.

Mariusz Lechniak, 35, claims that he only wanted to teach his sons the lessons they needed in order to become real men, ranging from 2 years old to 8.

His wife, Irena, begged to differ with her husband's parenting. Lechniak's wife confronted him after their 2-year-old son entered the kitchen holding a cigarette. She asked him to stop but he refused and started giving the boys beer.

She then submitted video clips of her children with cigarettes and alcohol and handed it over to police.
