KETTERING, Ohio, Oct 31 (Reuters) - Democratic vice presidential candidate Joe Biden got publicly “ratted” by his Halloween prankster wife Jill at a rally in Ohio on Friday.

After introducing her husband of three decades to supporters in this suburb of Dayton, the community college teacher slipped a toy black rat onto the podium.

“Some things never change,” laughed Biden when he saw it. “I probably should never let the press know this but Jill walked back up here a moment ago and you know what she did, she put a little rat on the podium. Everything is Halloween with this lady. Happy Halloween.”

Despite receiving a small rat from his wife, the Delaware senator said he had never heard her say such wonderful things about him as she had on the campaign trail.

“Some of you guys can appreciate that. It is hard enough getting it in private, but this is worth the trip man to have my wife stand up and say all those wonderful things about me. I love you Jilly,” Biden gushed.

Earlier in the week, Biden poked Halloween fun at Republican presidential candidate John McCain, proposing an “agent of change” costume was a poor fit for his fellow senator, whose policies he said were indivisible from those of the Bush administration.
