T-Rex

"That sounds so lame."

- T-Rexs' catchphrase T-Rex

T-Rex, or  Tyrannosaurus , is the child in a cool family.

History
Bart and Lisa met him when they were invited into 740 Evergreen Terrace. They were surprised to see all the obscure things that T-Rex had in his room and were even more shocked to find that he didn't own a TV. Bart, Lisa and T-Rex quickly became friends.

At T-Rex's birthday party, T-Rex mocked the present that Homer had made for him, and mocked Homer. Bart stood up for his father and attacked T-Rex, leading into a fight. This fight is what made the two families stop being friends.

Later, after Bart and T-Rex had forgiven each other, Bart asked T-Rex if he wanted to come to his to watch The Krusty the Clown Show. T-Rex said that he had to stir compost but Bart persuaded him to leave it. The compost started to burn and set fire to the Devil Donuts truck. After this, T-Rex and his family left Springfield.
