36        Number of times the word "shit" was uttered at CBS' upfront presentation (educated guess)

Most obscure trends, tie: Moustaches (Tom Selleck in CBS' "Blue Bloods"; Fox's "The Good Guys") and hyphens ("Detroit 1-8-7"; "Ride-Along"; "Hawaii Five-O")

Biggest star revelation: "Nikita's" Maggie Q, who improvised her speech at the CW presentation and charmed the crowd

Best pre-taped piece, tie: CBS' reimagining of research chief David Poltrack, whose comment at a convention last winter about "bullshit numbers" was turned into a rap; and NBC's opener starring Alec Baldwin as Jack Donaghy.

Biggest missed opportunity: With no party after the ABC event, the Alphabet should have screened that night's amazing penultimate episode of "Lost" for media buyers after its presentation.

Biggest victory lap, tie: The cast of "Glee," which performed "Like a Prayer" at the Fox upfront; and the cast of "Modern Family," the only cast to be flown out and placed on the ABC upfront stage.
