Michael Bluth is the second oldest Bluth son, but the most competent one. When George Sr. went to jail, it was Michael who was stuck running Bluth Company and keeping the family together. Michael's wife, Tracey, died of ovarian cancer two years prior to the first episode and left him to raise George Michael on his own.
Michael: What? What's going on?
Annyong: Ok. Mother want someone to go to my soccer game with. She don't want other soccer moms think that she is single mother. She old school.
Michael: I liked it better when he just said "Annyong".
Michael: (explaining ideas to his associates in a meeting) ...And we're back on track, and we're focused, and ... Buster. (who is assembling the bike) You can't do that in the snack room, pal?
Buster: Mom told me to stay away from microwaves. And besides, this is gonna be the most bitching fast bike in all of Orange County!
