Ben Stiller and Jack Black star as Tim and Nick best friends neighbors and co-workers whose equal footing is suddenly tripped up when one of Nick`s harebrained get-rich-quick schemes actually succeeds: Vapoorizer a spray that literally makes dog poop or any other kind for that matter evaporate into thin air -- to where exactly is anyone`s guess. Tim who had scoffed at Nick`s idea and passed on an opportunity to get in on the deal can only watch as Nick`s fortune -- and Tim`s own envy -- grow to equally outrageous proportions. When the flames of jealousy are fanned by an oddball drifter who imposes himself into the situation Tim`s life careens wildly out of control ... taking Nick`s with it.
