Much of Jeff Goodby and Rich Silverstein's work has a timeless quality to it. Not so the agency co-founders themselves, for whom a few too many grains of sand appear to have fallen through the hourglass. A busy 25 years in business together have left both men wrinkled, senile and generally a mess, judging by this humorous video invitation for Goodby, Silverstein & Partners’ 25th anniversary party on May 8. Thank God for the agency’s younger staffers, who are keeping their bosses sprightly, or at least not drooling all over each other. The makeup (nice jowls on Jeff, in particular) was done by Drac Studios, two-time Oscar winners for achievement in makeup, for Mrs. Doubtfire and Bram Stoker’s Dracula.
