Here's one that might be rather old. But it's probably my most favourite sexist joke!
God had just created paradise and Adam. At first Adam was enjoying this place very much, but eventually he got bored of being alone, so he went to god and asked if he couldn't create something for him to help him pass the time.
And God said: "Why sure! I have something great for you! It's called 'woman', my newest invention, but it isn't cheap".
Adam: "Hm sounds nice! Tell me more about it!"
God: "Well, it's another human being, almost like you, but slightly different. She would be a great companion for you. She would admire you and love you, she would tend to your every needs, be a great cook, and not only look extremely hot and be naughty in bed, but also be truly faithful to you!"
Adam: "WOW!!! That sounds great! How much would this cost?"
God: "An arm and a leg."
Adam (hesitating): "Oh... and what would I get for, let's say, a rib?"
