WHAT'S MY LINE? Alert

For those interested in witnessing important moments in television history unfold in real time, tonight's broadcast of WHAT'S MY LINE? on Game Show Network (3:00 am eastern) should be the first episode shown in the wake of panelist Dorothy Killgallen's death. Last weekend, GSN showed Killgallen's final WML broadcast, with mystery guest Joey Heatherton. Let's hope GSN handles tonight's broadcast more responsibly than last week's, which was ruined by a misplaced commercial interruption that omitted the majority of the second guest's appearance.
