I had sex with my teacher today!

A 1st grader came home one day from school and said to his dad, "I had sex with my teacher today!!!"

The dad then turned to his son, puffed up his chest and said proudly, "I'm impressed! I was in college before I had sex with my teacher!!" He then said, "Son, you remember that bike you always wanted? Well, I'm gonna go and get it now!!!"

The son then replied, "Do you mind if we go tomorrow, because my butt is still sore?!"
