Rooster

Loud, combative, and absolutely certain he's the smartest in the room.

Glenn Howerton is best known for playing Dennis Reynolds on It's Always Sunny in Philadelphia — a narcissistic, domineering personality who demands to be heard and refuses to be challenged, a character that reportedly draws heavily from Howerton's own intense, competitive energy. In interviews and behind the scenes, Howerton is known as the most driven and argumentative of the Sunny creative team, the one who pushes hardest, speaks loudest, and expects his vision to prevail. The rooster's pride, combativeness, and need to crow at the top of the pecking order fits him precisely.
