Dave
Dave only appeared in one episode of Modern Family, but he made a pretty huge impact. On Phil, that is. Both Phil and Dave went to the same university back in the day, and they remained huge fans of their college football team, the Bulldogs.
When Phil invites Dave over to watch the game, he thinks that Phil’s coming onto him. Dave had just gotten out of a long-term relationship and was ready to get back in the game, or so he thought. After a few awkward and “questionable” moments between them, he leaves Phil’s home before the game’s over, but not before planting a wet one on Phil’s unsuspecting lips.
