Obama boasted he's a better dancer than presidential rival old man McCain as he demonstrated his moves on Ellen's chat show.

The candidate appeared on a satellite link up from Miami and bopped about to prove that he's got the moves after his wife previously questioned his dancing skills.

Obama told Ellen: "Michelle may be a better dancer than me, but I'm convinced I'm a better dancer than John McCain."

After revealing his daughter's choice of Halloween costume this year he then joked he could dust off a pirate costume he wore as a kid.
