Bertha was an obese woman Jon dated in March of 1987. She originally called Jon as a wrong number, so Jon asked for a date. She seems to like Garfield and suggested to Jon to put some meat on his bones. She likes her steak rare and says, "Just run the steer by the table and I'll grab off a hunk!" She makes other appearance like at parties Jon goes to or a regular place like a laundromat. An other time she reappeared was in January 12 2003, where she met Jon and Garfield on a supermarket, but she had lost 200 pounds. Unlike most women who Jon tried to call by phone, Bertha very much enjoyed going on a date with Jon.
