Bigger Arms Quick? Bet with dad?

Hey, im 18. My dad and i have a bet. He says i cant put 2 inches on my arms by the time i get by for spring break. So, Triceps and bicept workouts. Who knows any that will kick my *** and make a strong burn. I normally bicept dumbell 20 then 15. after 1 set of 20 im fatigued and work on 15. So whos got a work out for muscle growth, not toning.
