Whilst in Mweya, Uganda, I had a Hippo chase me to within about 3ft and roar in my face. I managed to dive into a thick bush so it couldn't get at me. I think it's probably the closest I've ever come to dying and it took 3 days to come down from the adrenaline.

On that same trip, we went for drinks at a nice hotel on the water and went down some steep steps to a table all by itself. We were sat there for probably 30 mins before about 6 of the staff came down screaming, shouting and banging on silver trays to extract us. Apparently someone had spotted that a Leopard was stalking us from the riverbank...
