I'm sick and tired of the stories that you always tell
Shakespeare couldn't tell a story that well
See, you're the largest liar that was ever created
You and Pinocchio are probably related
Full of criss-crossed fits, you lie all the time
Your tongue should be embarrassed, you're a threat to mankind
