i was 19 in 1970 when it came out and having heard how funny it was when it came out and reading the reviews here and i finally rented it and watched it. i do not laugh once  a very unfunny flick  and i usually love reiner. i cannot for the life of me figure why this is seen as funny. i had not one chuckle. and i love comedies. oh well and at least now i know what all the shouting was about. not my idea of a comedy. go rent the navigator or the love nest by buster keaton  now those are comedy classics. if you rent this one  have a back up rental so your whole evening isn not a loss. score negative .
