I just got a survey call at work about broadband/dsl/etc. and at one point the person asked me to go to a website to look at something. She pronounced "html" as "hotmail".
You know, I bet that's no accident... It never occured to me before, but I bet that's what came up in some board meeting, people bandying about what word could be made from "html". Who'd come up with "Hotmail" entirely on their own?
