Profanity by today's standards? No.
The occasional G*d D*mn was mumbled in a few of those older movies.. and that was BAD for back then.
But I agree with you. Humor without 4 letter words it nice.
But I am rather old fashioned... I like a good dramatic movie, that does not have tons of random sex scenes thrown into it, or excessive profanity or T&A.
Hollywood.... thptthhh

!
BTW, you missed the Marx Brothers in that list... Clean, but slightly risque humor for the day.
