I swiped some stills of an animated ad that ran on Penny Arcade last weekend.
1) We pan across a majestic, sweeping vista of snow-laden mountains and fragrant evergreens.
2) The obligatory Hawtsome Fantasy Female appears, with attendant cleavage and come-hither glance.
3. OMG! Bear attack!
Apart from some additional text, that's the whole ad. The bear attack is never explained. The bear just pops up behind the chick. And then the ad cycles back to the beginning. She's trapped in a loop, forever menaced by Inexplicable Bear.
