Tonight the unthinkable becomes the thinkable. Tonight our wildest dreams come true. Tonight two beautiful men will take to the television screen back-to-back to bless American society with not one, but two cheeky sitcoms. Tonight our collective fantasy of watching the two best-aging actors in Hollywood will become a reality. Yes, we're talking about Rob Lowe and John Stamos . And, Tweeters from near and far took to their computers to share their feelings of hope and joy for this evening's meeting of the minds and faces.
