> The only possibility of one knowing bubble sort is by hearing about it on algorithms classes,

That's simply not true. I know for a fact that for me personally the bubble sort was the most "intuitive" algorithm because when I was in elementary school we had a computer club, and we were given the task for figuring out how to sort a list. My implementation was a bubble-sort, and at the time I had absolutely no knowledge of sorting algorithms at all.

Obviously different people will find different things "intuitive".
