"If I heard that while I was asleep I'd throw myself out of my window," joked one commenter. "I will literally bring my kid back to the hospital for an exchange if they laugh like this. How has she been smoking for 20yrs, as a 2yr old??" said another.

"She even uses it to tell me that's what she wants to play."
