Gramma

Gramma, whose correct name is be Grandma, is the grandmother of Greg, Rodrick, and Manny and mother to Frank. In Dog Days, she is given Sweetie. She tends to favor Manny, over Rodrick and Greg, but she denies this. She was married to Grandpa,Frank's father,but divorced him..

She likes to play bingo but is not as serious as some of the ladies. She also reads tabloids, which leads to problems, as Susan claims that tabloids are full of lies. However, Gramma seems to believe the tabloids, such as when she would not answer her phone because she said it erases the memory of the elderly.
