Uhura in a TV-first.
A recent issue of the National Review catalogued types of this action according to Annie on Community, and one instance of this action is responsible for Cordelia's prophetic visions on Angel.  Tom Brokaw claimed to have eyewitness reports of Liz Lemon doing this on 30 Rock.  In The O.C., performing this action helped distract Ryan from his precarious place atop a Ferris wheel, and that show later paid homage to a famous (*) upside-down example of this activity. A closeted football player does this to Kurt on Glee, and on the Star Trek episode "Plato's Stepchildren" Captain Kirk was forced to do this to Lt. Uhura in a TV-first. For 10 points, name this action more classically exemplified in a statue of Paolo and Francesca by Rodin.
