This is a sadly common conversation that I see at school:
person A
I'll beat you up!
person B
Well i'll get a knife and cut you!
person A
well I'll get my dad's sword and cut you!
person B
I'll get my dad's gun!
person A
I'll get my dad's shotgun!
and this goes on until both of their dads apperently have tanks, nukes, etc.
