A man, his wife, and his son are having dinner....

when their son refuses to eat the broccoli on his plate. His mother attempts to convince him to eat it, but to no avail.
The father suddenly says, "Don't worry, I've got this."
He stares at the child and says,
"!iloccorb ruoy taE"
His son then proceeds to casually eat his vegetables.
His amazed wife leans over to him and asks, "How did you do that?"
The man smiles and replies, "I just used reverse psychology."
