This is where I avoid the obvious 'corny' pun
The guys at LMB take a break from depicting fauna and attack flora in this one. Maybe the designer was eating corn off the cob and thought, "Hey, this would make a great idea for a random LMB ad!". Or maybe he was tired of elongating animals all the time, he figured fitting all the states on a corn would be much simpler.
The designer makes full use of Flash in this ad, and makes corn fly off in a swirl when you mouseover. You see, it's not normal corn that pops; it's quantum corn.
