“Don’t worry darling, you didn’t burn the beer!” – Schlitz
This has been a long-running sexist joke about a wife who has no talent for cooking and ends up burning everything. The ad mocks women who cannot do the only job that they’re expected to do, and that is to prepare hot—not burnt—meals for their husbands.
Instead of getting upset and putting his wife over his knee to spank her because he came home to another charred dinner, left ruined and producing black smoke from the pan, the husband consoles his wife. He tells her everything’s fine because she did not burn the beer. It appears the bottles of beer are more important than food.
The ad does not only demean women, but it promotes drinking. In this particular case, it implies it’s okay to drink even without eating. Drinking on an empty stomach affects your ability to think and leads to other health problems.
