Other mistake: When Striker says to Randy "You better leave sweetie, you might get hurt up here," watch Elaine who was trying not to laugh. (01:14:45)
Other mistake: In the credits, Kareem Abdul-Jabbar's name is misspelled Kareem Abdul-Jabaar. (01:23:40)
Other mistake: In the closing credits, Ann M. Nelson, who hung herself early in the film out of sheer boredom at Striker's longwinded story, is listed as the "Handing Lady" rather than the "Hanging Lady."
Other mistake: When Johnny reads in the folded newspaper, 'There's a sale at Penny's!', the viewer can read the headlines right way up - which means, from his side, he is holding the paper upside down.
Suggested correction: It's a reasonable bet that this was done deliberately as a sight gag. Throughout the movie, Johnny is portrayed as being somewhat 'special'.
