@lewt539, in all seriousness it takes me less than 30 seconds to uncoil the cable lock and string it through the seat rails, frame, front wheel and whatever I'm locking my bike to. I don't currently use a U-lock with that, however that'd only be another 15-30 seconds anyways. At first when reading 'lil brown bat's response I thought it was harsh, but really if you don't have a spare minute to lock up your mode of transportation, perhaps you need to rethink your plan and find a minute or two.

@lil brown bat, the 'low-hanging fruit' concept is exactly how it works around here. Bike theft and vandalism isn't running rampant, but it happens, and more often than not its either those who have abandoned their bikes, those who have nice bikes but barely take any precautions in securing them, or those who don't lock them up at all. A friend of mine picked up a bike from the side ditch in a road and cleaned it up. It was a beat up girl's bike, but he enjoyed not having to walk everywhere on campus. He rattle canned a matte black finish over everything (I mean everything, he's kind of a weird guy like that) but didn't buy a lock. It was stolen during his first class period. Same concept, he left it unlocked, so someone took it - didn't matter how junky of a bike it was, just mattered that it was unlocked.
