(When a child asked his/her mother)
"mom, does Humpty-Dumpty mother is a fat big chicken??"
"How mama duck know which one her daughter and son???"
Even a professor would laugh when heard this statements(i bet you will, don't cha)
Wohoo...that's what it called a fresh minded person.
If you feel like you want to do a serious jokes...you better start to think like a children. Meaning to say, what the children are thought are more likely innocence and indoctrinated.
The feeling of curiosity and excited to learn something new are the treasure essence for every children.
(They do not mind if they are wrong because the only way to learn something new is by doing a mistake)
