 The first "Weekend Update" anchor, Chevy Chase (qv), has said that  he modeled his catchphrase "Good evening, Im Chevy Chase and youre  not" after _"Eyewitness News" (1968)_ (qv) anchor  Roger Grimsby (qv)s opening line "Good evening, Im Roger  Grimsby, here now the news." However, Chases successor as "Update"  anchor, Jane Curtin (qv), would go on to use Grimsbys original  intro to open the newscast, and once, on the 22 April 1978 edition,  ended that nights "Update" with Grimsbys closing line, "Hoping  your news is good news."
