Common Sense Note
Parents need to know that Bill and Ted are slackers, have no respect for authority, and actively disobey their parents. But the tone is still very lighthearted and the characters seem to have the best intentions during their adventures through time. There is some comic violence and, appropriately, the Dark Ages is where the duo encounters the most life-threatening -- but still comic -- situations. Girls are treated as sex objects to the point that Rufus gives the boys two girls they met in Medieval England as a reward for passing their history test.
Lots of lighthearted sexual innuendo. Bill and Ted refer to all women as "babes" and take turns staring at Bill's mom's cleavage. Missy and Bill's dad make out in Bill's bedroom. Bill's dad is married to a much-younger trophy wife. Genghis Khan stops eating and starts making out with a servant girl. Sigmund Freud points his corndog suggestively.
Lots of comic violence and no one gets hurt. Ted falls down the stairs of a medieval castle and Bill thinks Ted has been stabbed and killed. Bill is almost stabbed as well, but Ted knocks the assailant out. Bill and Ted are almost decapitated. Billy the Kidd causes a barroom brawl and later shoots a light out in modern-day San Dimas. Genghis Khan destroys a sporting goods store with a bat.
Sparse salty language, including "dick," "dickweed," and "fag."
Bill and Ted are high school losers who don't pay attention in class and literally require divine intervention to save their grades. Ted's dad treats him badly and yells at him. They steal Ted's dad's keys and let people out of jail and generally disobey their parents. But overall, the message is to be good to one another.
Circle K, and the duo introduces historical figures to the delights of "mall culture."
