When I was a kid and my father took us to a restaurant for breakfast my father would always say to the waitress when she asked that question.
"Lookin at me"
Then, invariably she would say "How?"
He'd say again, "Lookin at me." staring at her like she should know what that means.
The waitress would always say tentatively, O, OK, take the menus and then bring him his eggs sunny side up. I don't know to this day if the waitresses knew what he meant but I suspect they just guessed not wanting to engage conversation with the weirdo.
Like father like son, "lookin at me" was the way I ordered my eggs because it reminded me of him. But I always had to explain it means sunny side up. I then realized it was a good way to engage conversation with the waitress and sort of break the ice for a little flirtation. Dad must have known this, but what he didn't get was at his age it was just weird.
After dad died I changed my preference to "over light."
