Leading up to Halloween, AT&T and BBDO New York have been running a campaign called "Ghostbombing," in which ghosts, goblins and ghouls engage in a little freaky photobombing to promote the HTC OneX mobile device. Now, with the big day upon us, the telecom has ghostbombed one of its recent TV commercials, "Whiz Bang," by inserting all sorts of spooky creatures into the quick-cut footage. You'll probably need to rewind this one a few times to catch everything. And speaking of BBDO and Halloween, you might also want to check out the agency's fright-night Snickers spot, "Horseless Headsman," which we posted a few weeks back.
