Common Sense Note
Parents need to know that Looney Tunes is a classic cartoon that's been through many reincarnations starring its popular characters such as Bugs Bunny, Porky Pig, Wile E. Coyote, and Daffy Duck. Older episodes reflect the cultural leanings of the time and often show stereotypes of minorities and women that are offensive by today's standards. This cartoon is probably best known for its use of physical gags for humor, particularly between rivals such as Sylvester Cat and Tweety Bird, so you'll see characters hit, kicked, crushed, stretched, tied in knots, tied to a railroad track, shot (no blood or injury beyond a blackened face), and blown up, none of which lasts beyond a scene change.
Sexual
Content
Violence
Cartoon-style violence, and lots of it. In many cases, the stories follow one character's efforts to maim or kill another, all of which is played for laughs. Characters are crushed, hit, kicked, punched, conked on the head with various hard objects, shot, and blown up, only to return without so much as a scratch for the next scene. Some wield guns and use them to threaten their enemies.
Language
"Stupid."
Social
Behavior
This classic and oft-reinvented cartoon is a prime example of no-holds-barred entertainment, as it so often relies on physical gags and violence for laughs. Older episodes also feature a lot of racial and gender stereotypes that were common for their era but are a shock to the senses now, particularly in the case of African-Americans and Native Americans, who are depicted in a derogatory way by modern standards. Some versions have content like this, as well as violence such as suicide gags; some versions edit it out, but many don't.
Consumerism
Looney Tunes is a longstanding and multifaceted marketing conglomerate, all inspired by recognizable characters such as Porky Pig, Daffy Duck, and Bugs Bunny. Their images grace everything from snack foods to children's books, and they've starred in numerous TV series and movies.

Alcohol
In some stories, characters take pills, smoke, and drink what's assumed to be alcohol, from which they usually show signs of being drunk (wooziness, stumbling).
