Possibly upset with the announcement that the U.S. Postal Service could be bailed out by the federal government, a moose on Sunday took out its frustrations on a neighborhood mailbox.

YouTube user lronet captured the video of the young male moose in the Jewel Lake area of Anchorage. Although "going postal" might be an easy joke to make, it probably isn't the real reason the moose decided to spar with the mailbox. As moose's antlers grow during the summer months, they're covered in a velvet that support growth and nutrient delivery to the antlers underneath.

Prior to the traditional autumnal mating -- or "rutting" -- season, the velvet dries out and sheds from the antlers, allowing the males to duel for the potential affections of the females. To precipitate the removal of the itchy velvet, many moose will rub their antlers on nearby trees or, apparently, mailboxes. In this case, the moose seems less like it's practicing for a duel than it's trying to work off the velvet. Or maybe it was just feeling particularly unpatriotic on the tenth anniversary of Sept. 11, as it knocks off the small American flag mounted on the mailbox early on.

So does the mailbox withstand the assault from the irritated ungulate? Well, you'll just have to watch and see -- although the color commentary from the cameraman and two bemused friends will keep you chuckling, especially the unfortunate owner of the mailbox. "What am I gonna do?" he asks in the video. "Call the police, have them arrest the moose?"
