Joe Biden bit his wife Jill’s finger onstage Saturday at a rally in Council Bluffs, Iowa.

She was introducing him at the first stop of an eight-day, 800-mile road trip through the first-to-caucus state.

She must have looked good enough to eat…

As Jill Biden flung an arm wide to make a point, her husband theatrically dodged her hand — then, on a second pass, gave her a playful chomp on her fingertip.

She took the nibble in stride, laughing along with a crowd of about 200 supporters.
