Birthday Bust
On your birthday you take the age that you are turning and dived that number by 4. If you get a irrational number (like 3.5 or 5.6) you round down. Once you have this number you must bust that many times on your birthday.
Jeff: "hey birthday boy, how many time do you have to birthday bust today?"
Jerry: "only 4 times."
Jerry: "only 4 times."
