Vince Vaughn and Owen Wilson try to rekindle the comic charisma that worked in “Wedding Crashers,” but with no help from the script (which Vaugh co-wrote). They play 2 laid-off salesmen who get gigs as summer interns at Google with hopes of landing a job for them and their team of misfits. It’s been a plot staple since “Bad News Bears:” This seemingly hopeless group comes together to beat all odds. Although there are some mildly amusing supporting characters, Vaughn and Wilson flail around with pitiful patter and lame jokes. There’s plenty of energy, but not many laffs.
