Abe introduces Abbie to Sean Connery, who happens to walk by dressed as a U.S. Army officer. Connery was actually in costume for the filming of The Presidio (1988), and did the cameo appearance in between takes.
In many scenes throughout the movie, Billy Crystal is seen wearing either a sweatshirt or a t-shirt from New York University. Billy Crystal graduated from NYU with a Bachelor of Fine Arts in 1970.
At Abe's funeral, there were flowers surrounding and on top of the casket. At Jewish funerals, flowers are not sent because it signifies a joyous occasion.
Abe: Sweet dreams to my fingers, sweet dreams to my knees. Sweet dreams to bellybuttons that go in and out. Sweet dreams to all the little tushies in the world - the big ones, too, like the waitress in the bowling alley!
