one day, little billy came home from school.

his mom asked, "what did you do in shcool today billy?"

Bily replied: "I got an A on a spelling test, had a math quiz, and
had sex with my english teacher."

"you did what?? go tell your father what you just said." said mom

so little billy goes up to his father.
"dad, mom wanted me to tell you that I got an A on a spelling test,
had a math quiz, and had sex with my english teacher."

His father repied "son, today you're finally a man. let us go out and
celebrate by buying you ice cream and a new bike."

to which little billy replied:
"the ice cream sounds ok, but could we hold off on the bike for a while?
my ass is killing me."
