I just love it when she starts screaming for no random reason. For example, I thought it was hilarious in the episode Tori Fixes Beck and Jade when she calls Andre and starts screaming "ANDRE THERE'S A TREE IN MY LIVING ROOM! AND SOMEBODY STOLE MY CEILING!" Andre explains to her "Grandma, you're just in the backyard." She shouts "OH!" and starts laughing hysterically.
