Strange keyboard characters

[TitanTiger]

My friend's Macbook is acting weird. All the keys on the keyboard type correctly except the "H" and "V" keys. When typing a lower case "h", a superscript dot appears. Shift-"H" gives you a capital "O" with an accent mark over it. The "V" key doesn't do anything but give you a sound like you're running up against the end of something and can't input a character.

I've monkeyed around with the input menu to make sure US Qwerty was the only keyboard layout selected. Tried switching to something else and back to US Qwerty. Still nothing.

Any ideas what's going on here?
