Dumber by the Minute

Even though slightly (way) over the hill, the jobless boys squeak into the Homeland Academy in Las Vegas. They move into a Homeland frat house where they discover the old locker they brought with holds an ancient beer mug that shatters and reveals one's great grandfather built the lost brewery in the desert for Al Capone and hid the secret map in the beer mug. Their search brings out a wandering 95 year old mobster, the entire Las Vegas mob, the head of the Academy and a fellow student great grandson of Capone, all intent on a "to kill for" search worth a billion.
