I did vote for Jamie, but after much thought, I concluded that Hal is the worst-behaved. Even though he's not on the polls, he's the cause of her second-worst rage (Red Dress,) the worst being the heat (Traffic Jam.) He can be counted as one of her boys since he has to squabble with them on Bacon Day. Here are the things he's done, many of them in the presence in the boys:
Beaten up Craig
Beaten up a clown (he threw the first punch)
Bitten Francis in the leg
Beaten up Francis and Reese
Bashed a hole in the wall
Cut work regularly
Convinced the boys to cut school
Given the boys his I.D. (What good can come?)
Used underhanded tactics in basketball
Set things on fire and then hid them.
Lied (too many to count)
Screamed like a monkey to fend off the neighbors
Used the woodchipper as a toy
Drove Malcolm out of the house and then...
...admitted to favoring him to get him back
Built a bee shooting robot
Refused to attend a funeral
Shuffleboarded Jamie
Gamble to excess
Cheated
Brodcast unauthorized radio
Burned Craig's house down
Hidden incriminating things in the couch
Built a speed bump
Stole and then destoryed a car
Drank to excess
Paid Malcolm to take blame for something he did
In "Monkey" alone:
Whacked stuff with his golf clubs
Picked a fight with a big guy and a guy in a wheelchair
Fought a monkey (and nearly lost)
The boys have done many of these alongside him, but he's supposed to be the adult, so it's mostly his fault
