Dave and Penny (Zachary Knighton and Casey Wilson), Happy Endings

We came thisclose to a hookup in the season finale, but TV sitcom conventions called for a triangle (hey, Alex!). Dave's dorky, straight-man ways could be the perfect balance and answer to Penny's kookiness and perpetual single-dom. Plus, that look they gave each other in front of the fountain was basically code for "I'm seeing you in a totally different way."
