FINAL TALLY: Mario Lopez did not receive an adequate education at Bayside High, at least not in the area of staying faithful. Plus, his diva attitude makes us gag. But Matthew McConaughey is the clear winner here. His immaturity is appalling, and we practically want to invite Camila Alves over for a good cry and some babydaddy-bashing. Matt, the award for Sleaziest Bachelor has your name written all over it!
