@JGoldman10,
I'm not sure what's happening for you.
I tried "tom and jerry" as well as "daffy duck" as a google image search. No sign of porn on daffy duck in the first 20 pages (I gave up at that point). One item that maybe maybe maybe could be slightly titillating using "tom and Jerry"on about page 6 of a google image search.
Mebbe google.ca is cleaner than google.com?
I really don't know.
netnanny is supposed to be the best option, though I've determined that I can put parental controls on my Kaspersky security which can be manipulated to be a minor league porn filter. Probably not tough enough for your needs.
