Years ago staying in our onsite van at Yarrawonga. Choked on a bit of bread from a hamburger roll. Thought my time was up and wife was punching me as hard as she could on my back which eventually dislodged it. Didn't feel quite right so headed home to Melbourne with wife driving. By the time I got home the whites of my eyes had gone red. Apparently burst all the blood vessels and had actually popped them out a bit. Looked evil for quite awhile.
