A son asks his father about being a man. The father says, "Son, all men are just monkeys."
The son is shocked and then the father continues, "But there are three kinds of monkeys. The first monkey just eats bananas and throws his shit all day. The second monkey gathers bananas to give to female monkeys in exchange for sex."
And the third one?" asks the son.
"Well," says the father. "the third monkey spends all day thinking how he can grow a banana tree."
