Malcolm wants the car, but Lois won't give it to him. Jessica (who's sleeping over while her dad is in jail again) let's him in on her secret to get things from Lois - sympathy.
In essence, Malcolm and Lois start sharing stuff and opening up to each other. At the start Malcolm did it to get the car, but then he started to care for her. Then it was just about their relationship. As Jessica said, he became like a girl.
Eventually Malcolm told his mom the truth and then ruined Jessica's make out session with her Chinese American boy friend Mike.
Resse gets a penpal from China. Due to his incredible ignorance, he decides to mail himself to China to beat the guy up.
Once in the crate, Dewey uses the time to torture Reese (who thinks he's actually going to China) with various methods. Eventually Lois finds out and Dewey explains what happened. She approves of the torture and lets him continue.
While Malcolm is crying on Jessica's shoulder, Mike and Dewey meet. Dewey quickly forms a plan on the spot to have Mike open the crate. Reese comes out and acts stupid, and then Mike beats the crap out of him. Mike is a muscular guy.
Hal has a fear of bees. He apparently destroyed the hive and made honey, but left one alive. This bee then torments Hal until Hal eventually wrecks his car trying to kill the bee.
Someone should of told Hal that honey bees don't have stingers.
