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.
