I used to think so too ( Sorenstam too ) when I was only watching TV.
Basically I think there are 4 categories of pros ( in one set of definition ).
1. Kiss Up - Nice to whomever can give them somethin including while they're on TV - DL III, Paul Azinger, etc..
2. Kiss Down - only nice to people who doesn't count ( and nasty to TV or PGA officials ) - VJ, etc..
3. Nice all around no matter what - Ben Creshaw, John Daly ( when not sick ) etc..
4. Leave me the **** alone loner - Greg Norman, Jeff Sluman, Tiger etc..

But many of them change as they age and succeed/fail so depends on when you catch them... If you catch them while they're running to a toilet, noone's gonna be nice to you..
