Here's a brand new Nike commercial starring Tiger Woods in which his (dead) father's voice-over asks if he "learned anything."

Lesson #1: Never ever keep sext messages.
Lesson #2: Never ever keep golf clubs within reaching distance of an angry wife.
Lesson #3: Pancake house waitresses should not necessarily be trusted to keep their mouths shut.
Lesson #4: Same goes for cocktail waitresses.
Lesson #5: And porn stars.
Lesson #6: Especially porn stars.
