I've got a couple more instances in which "The Numbers" of 'Lost' came into play during episodes of other TV shows.
On the night that Liz Lemon thought she got pregnant, Dennis Duffy was wearing an ISLANDERS jersey (Thanks, Brent!) with the number "8" emblazoned on it. ('30 Rock')
Behind Dick Hollister's desk at the newspaper, there was a publicity placard announcing the 8 PM broadcast time for 'Jetman'. ('He & She')
In the camel race of Unagatta, Paul Hamilton rode Bodiceaa, camel #4, to victory. ('Supernova')
There is a weirdly shaped #8 hanging on the wall behind one of the main characters. ('Pulling')
The license plate for a police car arriving at the airport was #444. ('Poirot' - "Lord Edgeware Dies")
Vic Tyler was staying in Room 16 at the Victorian Park Hotel. ('Life On Mars')
A "Scared Straight" sketch featuring guest host Shia LaBouef took place in the 16th Precinct headquarters. This would be in Skitlandia, the sketch dimension. ('Saturday Night Live')
And finally, from the mother-show itself.....
From a hidden suitcase that also contained binoculars and Ben's kick-ass baton, Hurley helped himself to a cache of DHARMA Initiative crackers. Ben then pointed out: "You do know those crackers have been there for 15 years?" ('Lost')
If you make any sightings of the 'Lost' numbers on other TV shows - past or present! - let me know.
