How are "i.e." and "e.g." pronounced?

i.e. stands for id est (Latin), which means "that is". You use it to link in a deeper explanation about something. Pronounce it "eye - ee".

e.g. stands for exempli gratia (also Latin), which means "for example". You use it to link in an example of a more generic term. Pronounce it "ee - jee"

For i.e. I usually say "that is", occasionally "eye-ee".

For e.g. I always say "for example".

Just pronounce the letters: "Eye eee" and "eee gee".

I have never met anyone who actually said "id est" and "exempli gratia", which is what they really stand for.

I can't believe this wasn't addressed in the Oatmeal Comic but I usually say the letters or replace it with "for example" (and now, thanks to the comic, I'll replace it with "in other words" instead and use e.g. when I mean "for example").
