Ray Drecker's penis isn't the only thing that's big about Hung.

The series premiere of the HBO series delivered 2.8 million viewers in its 10 p.m. timeslot Sunday; combined with its midnight replay, the show drew 3.7 million viewers.

Those figures make Hung - a light-hearted drama about a depressed high school coach who becomes a gigolo - the highest-rated HBO premiere since John From Cincinnati.

Undoubtedly helping Hung's cause was the major ratings garnered these days by True Blood, which preceded the new show.

Sunday's installment was the series most-watched ever, bringing in 3.7 million viewers in its 9 p.m. timeslot, and 5.1 million overall.
