interesting tidbit: tiger's speed dial

Tiger offers an interesting tidbit in Golf Digest.
On his speed dial of his cell phone are:

1. Mark O'Meara
2. Notah Begay
3. John Cook
4. Charles Howell, and
5. David Toms

1,2, and 4 were no surprise, but John Cook and
David Toms were. Also surprising are the golfers
not on speed dial like:

1. David Duval
2. Darren Clarke

But not surprising are these people who didn't make
the list:

1. Phil Mickelson
2. Sergio Garcia
3. Vijay Singh
