The most annoying typo error...

[Russell E. Owen]

It hits me often enough that I wish it were a syntax error or that one 
could enable a warning for it. But I usually track it down fairly 
quickly.

To those who wonder how such a thing could happen, I personally find it 
creeping in occasionally when editing existing code, e.g. via sloppy 
modification of an argument list.
