It Begins

The master said good-night to some very exhausted first-day-of-school kids. The last door at the end of the hall is K's.
The master: Good-night, son.
K: Good-night, Dad. Hey, Dad? Could I please keep my sideburns?
The master: K, you know your mother is going to throw a fit about those. I don't think there is a chance she is going to let you keep them.
K: (crestfallen) I know, but I found out the chicks dig sideburns.


Wondering exactly how did he "find out" this information? And planning on a trip to the barber TOMORROW!
