Fast National ratings for Thursday, May 29, 2014.

Buoyed by the aggressive promotional efforts by the show's stars and creative team, "Undateable" got off to a decent start for NBC, helping the network join a three-way tie for Thursday among young viewers. Overall, of course, there was very little competition as a CBS repeat of "The Big Bang Theory" was the night's most watched program by a wide margin.

NBC is boasting that "Undateable" had its best summer comedy premiere numbers since 2004 and the immortal "Come to Papa."

The "Undateable" premiere far outdistanced most of NBC's Thursday comedy performances in-season, built slightly on its "Hollywood Game Night" lead-in in the key demo and was steady between two double-pumped episodes. That's good news for Bill Lawrence and company. Of course, "Last Comic Standing" was NBC's top program for the night.

Similarly, "Hell's Kitchen" got FOX's best results and was the reason FOX also tied for Thursday's key demo lead, but the network has to be at least somewhat relieved to see "Gang Related" steady in its second airing, rather than plummeting like the second week of "I Wanna Marry 'Harry.'" 

The relatively good news for Thursday's summer scripted shows did not, however, extend to ABC's "Black Box."

On to the numbers...

Among adults 18-49, CBS, NBC and FOX all averaged a 1.3 rating for Thursday night, tying for the top spot in the key demographic.
