I think the idea is to make it light...if it''s too serious, nobody would give the guy a second chance.  We don''t have anything to do with his personal life, but it''s our part as designers to create an advertisement that is catchy and current, at the same time, not too derogatory and direct.  You don''t really have to attack the infidelity issue, but if you can change the negative image into positive...why not think of  a way to help Mr. Tiger Woods get back on track again?  It''s our job people, make it wise.
