Grapefruit. Love it plain, both the white and the red. Hate it with sugar. I eat grapefruit 4-5 times a week. I never order it in a restaurant, though, because some places put sugar on it even if you specify without.
I guess that’s technically sugar “on,” not “in,” but I think it still counts.
Favorite pinball machine.
All-time favorite pinball would be Gottlieb’s “Royal Flush,” from about 1975 or so. Typical Gottlieb asymmetrical playfield, a weird way to earn bonus points by making poker hands, and the chance to change the point values of the drop targets during play. Given all the pinball machines I’ve played in my life, it still stands out as one of the most challenging and fun.

Favorite judge.
Do justices count? Can I say Elena Kagan? If not, PM me, and I’ll come up with another answer.
Favorite vice-President (US) who never became president.
Al Gore. I’d like to think a ton of progress would have been done on global warming by now. For the want of a chad…
Fave high school prank
Probably the one we pulled on our band director at a Christmas concert. We started playing Sleigh Ride, and after the intro we all dropped out except for the xylophone player. He played the set of triple notes by himself in the wrong key and had this dumb look on his face like he was somewhere else. We then gave the band director his Xmas present. He took the whole thing with grace and humor.
Favorite college prank
Those were stocks, not bonds. 
Disassembling a VW Beetle and then reassembling it inside a student’s dorm room (allegedly done at MIT).
Favorite graduate degree you wish you had?
