Brock's Bad Temper (And The Time Machine)

Brock has a bad temper, can he get it under control?

Brock
has a bad temper, he just can't seem to keep his anger under control.
His sister, Brenda, is known as the kindness queen. She warns Brock that
if his temper keeps up, he will wind up taking a trip in the bad temper
time machine. Brock thinks she's crazy. She tells him that she used to
have a bad temper too but all that changed after a few trips in the time
machine.

Brenda tells him that one night she was
putting on her pajamas and the next thing she knew, she was in another
time period. She was also getting ready to receive an old-school
punishment. Brock doesn't believe her and says it could never happen to
him.

Then one night after a rough day at school he is
transported back in time in the time machine. Will his experiences show
him that having a bad temper is not a good thing? Will he realize that
the modern-day consequences of his actions are not that bad? Join Brock
as he gets in trouble, goes back in time, and finally learns to get his
temper under control.
