Petunia

Petunia once went on a date with Fry when Bender's dating service set them up but she was more interested in Sal, even though he was on a date with Leela. Every Xmas she is prepared for Robot Santa by leading him into a trap. She once saw Bigfoot the monster truck crushing cars at the county fair. She may have had sex with Fry although when this is implied it is actually Leela's dream in The Sting.
