Nick Kelble and Hayley Roll recently visited the Cincinnati Zoo to celebrate their 1 year anniversary.
One of the animals they were most excited to see was Fiona the Hippo -- who ended up taking a front row seat when Nick popped the question.
Nick & Hayley's engagement photo has since gone viral, specifically because of Fiona's hilarious little face. [Fiona has already been somewhat of an internet phenom this year, but damn, this photo of her takes the cake IMO.]
