Mike calls Susan because he has some free time and wants to come over and teach MJ to ride his bike. She says MJ's excited, but then she turns and looks out the window to see MJ riding the bike perfectly, thanks to Jackson. She goes outside and reprimands Jackson for teaching him, since Mike wanted to. Jackson asks why she didn't tell him, but Susan -- being the deliriously self-absorbed creature that she is -- assumed Jackson would not have to be told not to steal a father's precious moments. Jackson says MJ kept asking him, and he couldn't say no, because MJ said "Pweeeese." When Mike shows up, Susan brings MJ out all padded in a million layers of protective gear. She's telling him he needs to pretend he can't ride. To achieve this, he has to fall down. He doesn't want to. Then they go out and he rides like a pro. Mike can't believe how fast he's picking it up, but is too stupid to realize this is not the kid's first time riding. Susan stops MJ and tells him quietly he has to fall and shouldn't be scared. Then he keeps riding but comes to a complete stop and then topples over. Mike runs over and tells him to remember to put his foot down when he stops. Or, you know, don't listen to your insane mother. Turns out MJ's actually hurt. Susan looks appalled at herself. As she should be.
