'I'm gonna quit school and become a rockstar!' ... then he showed up to class wearing a t-shirt that said 'I like pizza.'
'I'm gonna eat the whole cake!' ... then he took one bite and said it was too sweet.'
'I'm gonna start a rebellion!' ... then he fought with his mom over the last slice of pie.'
