My Uncle Bill taught me how to count in Roman Numerals. Of course... it took me a long time to realize what was going on.
Our family is into the cheaper fireworks and Roman Candles give the most bang for the buck. We would sit on the beach and watch the firecrackers go up to the sky and Bill would start yelling.
"Aye! Aye-Aye! Aye-aye-aye! Aye-Vee!"
