Disturbing Things In Sixteen Candles You Only Notice As An Adult

Intoxicated women are used as a comedic elements several times in the film. First, Caroline is drunk and rowdy at the party, then alternates between being drunk and passed out in the car afterwards. At one point when she comes to, after Jake has "given" her to Ted, Jake tells her that he's Ted and vice-versa; her ensuing, drunken confusion is clearly meant to be funny. 

Once Ted and Caroline are on the road, Caroline acts recklessly, drinking, messing with the controls, and throwing booze bottles out of the window. She also feeds Ted a birth control pill and laughs hysterically. Then, when she's again passed out, Ted and his friends attempt to get a photo of him with her to prove the encounter occurred. 

The second character whose intoxication is used for laughs is Sam's sister Ginny, who's high on muscle relaxers at her wedding. She took them to deal with discomfort from her period, but clearly took too many. She stumbles around, slurs her speech, sits in a pew during her walk down the aisle, and pulls pieces of her dress off in front of the guests. 

But rather than postpone the ceremony or help her, everyone props her up and does everything to keep the ceremony going. It's clearly supposed to be hilarious, but it's disturbing to watch her stumble around, the cameraman gleefully capturing every second on film. Even the groom thinks it's all a gas.
