No es la playa pero no está mal

It's the first week of holidays and everyone has gone to Mallorca on a school trip. Except Guti and Saúl, which are grounded and bored stiff in Madrid. They are not throwing out their holidays, tho, given that their end-of-school trip is going to be breaking in the high school and ravage it from top to the bottom. And let the Mallorca guys die of envy. And for once be the kings of the school.
