technically....and by definition
Willy says...anything with a K in it is funny...OK.
so it's odd that he exchanges "Come in" with "Enter!!!"
but Willy delivering the line "Enter!!!" is funnier than the K "Come in"....
maybe Walter is the exception to the rule :)
maybe it's the exklamation? :)
i bought the DVD and watched some extra footage with Phil Silvers doing the Willy part...not funny in the slightest, even though i really like Silvers in many films...i also watched the 1995 version with Peter Falk playing the part...YES Peter Falk...not funny.
i always feel that Neil Simon relies on the right person delivering his lines...
the casting for this film was perfection.
