Vince Vaughn and Owen Wilson are successful watch salesmen whose company closes. Without job skills (Get it? They're salesmen.) they take a chance by joining Google's intern program. The get paired up with other "long shots" and have to compete for jobs.
This is a by the numbers comedy. You have the hard ass guy in charge, the hidden authority, the helping teammates with their flaws or fears, the evil dick who goes out of his way to make enemies, etc.
Oh, and a boatload of titties (in one scene only).
You'll only like it if you like the actors involved. Even so, it's still only worth a $1 rental or Netflix.
