Point, The Easter Egg - Opening Credits

This film, animated by Fred Wolf with songs by the late Harry Nilsson, has three written messages hidden at the beginning of the opening credits. Each message only appears on-screen for two or three frames. Single-frame through the credits, and the following messages will appear:

"NILSSON HOUSE MUSIC INCOM
MADE JUST FOR THE MONEY INCAS"

"NILSSON SINGS GOOD SONGS INC
MURAMKAMI WOLF FILMS INCAS"
(This message appears twice)

"HARRYHARRYHARRYHARRYHARRY
FREDFREDFREDFREDFREDFREDFRED"

The above messages are humorous, even though I don't know what they mean by "INCOM" and "INCAS".
