You too, eh. When I was a kid, I thought everyone had green eyes (because every one of my cousins and neighborhood playmates did). Then my family moved to a different state...and I was definitely in the minority.
Did just a bit of research...here's a (kind of) break down of the US population:

And still came up empty. What is of current interest, though, is the relationship of iris color as a risk factor for ophthalmologic and skin disease. The color of the human eye results from variable amounts of pigment within several separate compartments of the eye's structure, and those pigments are similar to the pigments responsible for skin coloration. Skin pigmentation is one factor in cancer risk, so there is some interest in iris coloration as well. I discovered a research study from 1990 whose goal was to classify iris coloration into 5 categories, and to see if different clinicians would classify patients' eyes in the same categories.
In a sample of 324 patients from 5 “urban clinics” in Massachusetts and Maryland (therefore spanning many socioeconomic and racial groupings), those investigators reported:
32% blue/grey irises
15% blue/grey/green irises with brown/yellow specks
12% green/light brown irises with minimal specks
16% brown irises with specks
25% dark brown irises
As for what floats my boat, it's gotta be eyes so dark...you can't distinguish the pupil. Married one of those.
