One day, while Goku was taking fish back to his house, Bulma ran over him and Goku attacked. This led to Bulma having to shoot Goku since he was breaking her car. "Ow ow ow! What was that for, monster?!" exclaimed Goku. "Don't call me a monster, boy! You're the one attacking me!" shouted Bulma. "But that monster you were in tried to steal my fish." complained Goku. "Monster? Little boy, have you never seen a car in your life?" asked Bulma. "That's a car? Grandpa Gohan told me a lot about those! He also told me about cities and girls." explained Goku. "And what did he tell you about girls?" "He told me that if I ever meet one, I should be very polite." said Goku. Bulma became fond of Goku then and let him invite her to his house.
