President Barack Obama came face to face with a man wearing a horse head during a visit to Denver on Tuesday night.

Like any seasoned politician, he didn't miss a beat.

Obama appeared surprised at first, then chuckled and shook hands with a puzzled, bemused look on his face as he greeted people on a downtown street.

It's not clear if horse-head man said anything to the president, but photos of the strange encounter have gone viral as soon as they were made public.

Obama then headed to a bar to shoot pool with Colorado Gov. John Hickenlooper.

He was in town for a Democratic fundraising event.
