My last name, Houde, gets mispronounced quite often. The correct way to pronounce it is like "hood". Here are some of the more memorable ways people say it:

"How'd" - By far the most common. It does make sense though.
"Who'd" - Like "how'd", I can see how people got this one. One of the professors in my department keeps saying it this way and I keep forgetting to correct him. XD
"Hode" - Um, okay. Not sure how people forget the U on this one.
"How-OO-day" - ... I just don't know.
