Two grown men are hanging out at the zoo together (look, it's a commercial. It's not supposed to make much sense.) One guy holds up a camera and tells the other that he should jump into the bear's den because "I want to get a picture."
The second guy is skeptical- gee, isn't jumping into a fenced area containing an untamed animal with claws and sharp teeth dangerous? "Nah" is "friend" reassures him, "it's winter. Bears hibernate."
Oh ok then, no problem! Moron boy proceeds to jump over the fence. Freeze-frame, and the words "Not Smart" appear on the screen.
Then the scene switches to CarMax, and the guy who was jumping into the bear's den is now jumping into the back of a truck. Ah, get it? This IS smart- buying a truck at CarMax! And the other friend, who apparently has a camera surgically attached to his hand, takes a picture of him jumping in. Brilliant.
So the message is "don't commit suicide by jumping into a bear's den, even if your retarded friend says its ok. DO buy a truck at CarMax, because you'll get a good deal." Seriously. Is this the best you can do, CarMax? I find it hard to believe that a guy dumb enough to jump over a fence at the zoo holds down a job that pays enough money to buy a truck. Or dumb enough to stay friends with a guy who thought it would be fun to get a picture of him being mauled by a non-hibernating bear. But that's just me.
