For my six birthday, my mother gave me a music box shaped like a miniature Persian cat. The cat's head screwed off and the body was hollow and filled with peppermint schnapps. She told me not to drink all of it in one sitting (can you tell what an awesome parent I have?), but I did anyway. It only amounted to about 2 shot glasses, but for my age it was quite a lot. And it was FANTASTIC.

There was also a 1955 Dom Perignon for my birthday, courtesy of my grandfather. No other champagne I've tasted can hold a candle to that experience.

After that, it all kind of blends together. As it does when you drink as much and as often as I do. Memorable Inhalations might be worthy of another thread, though...
